Rule

Ignoring the flareless butt plug shape for a moment - what prevents you from sticking a flat-based beer bottle into the sand, and why would you choose a shape that can’t be put on a table or upright in a fridge?
It’s a pretty looking bottle though :)
- Reminds me of the PET bottle before refined into to the actual bottle:
  PET-Rohling (German article)
  
  The long-time tradition of sticking objects into one’s anus transcends borders :)
  Oh wait…you were referring to bottles that can’t stand upright, weren’t you?
  
  I used to have one of these! I delivered plastic to one of the bottle companies in Germany with my dad, and I was given one.
  
  Ah yes, my first dildo.

  Thought this was going another direction...
  
  Nothing. You just have to "shape" the hole a little more.
  I do not recommend sticking a beer bottle into the sand when it's 30°C though. That's a sure way to get disgustingly warm beer
  
  Hah! I mean, that’s also an option.
- You’d need no either dig a small hole or use way more force to push a normal bottle into the sand
  
  If I was really determined to make my cold beer warm by putting it into hot sand, that is an effort I would be willing to make. But then I wouldn’t have the danger butt plug as a souvenir afterwards.
- People who live near the beach you're trying to drink on. Nothing says "I dont respect nature or your home" better than bringing a bunch of disposable beer bottles that you will statistically probably leave in the sand or throw into the ocean as soon as youre done with them. This is probably more a rant about overtourism than it is about beer bottles, but seeing a bottle thats designed to bring to the beach made my blood boil.
- It would make sense for bars with ice chests that served bottled beer in glasses
- It's glass, and you can read up more on how the Serbian-war started...

Newsflash! Every beer bottle can be put in sand quite easily already.

Without a base, without a trace.
- Hollow and made of glass? Don’t shove it in your ass.
  Probably the only bottle you can use for sex is a champagne bottle. Since those don’t break as easily.
  
  I wonder... What if you removed the wires holding the cork, inserted said cork end of the bottle, and shook the bottle mercilessly. How would the ER get to the cork from that far up?
  
  as easily
- Tie a string around the top and launch it into someone's ass with a spud cannon. Rectal harpoon.
  
  Then pull back with Scorpion line: Get over here!
- Holy cow, this is great. Thank you. I will be stealing this handy little phrase.
  
  I can't take credit for the phrase. On the podcast Jordan Jesse Go with Jordan Morris and Jesse Thorne, they celebrate Anal August. It's a month where they celebrate anal toy safety.

Hold my beer.... WAIT! NO!!!! NOT LIKE THAT!!!!

We’ve come full circle
- At least these ones are flared at the base.

Why would you want to put a bottle in the sand? Wouldn’t the sand just warm up the beer quicker?
- In case you don't want it in your ass?
  
  Why would you want to put a bottle in your ass? Wouldn’t your ass just warm up the beer quicker? Hmmm... although if I shove ice up their first...
  
  But what if you wanted that bit of extra texture
- Yes, but I think the idea is that it won't tip.
  edit: I'm more of a spirits guy, but I always thought rocking whiskey glasses were really cool. Apparently they were designed to house liquor or wine without spilling on a sailboat. I even have a decanter that goes with a similar tumbler set, though I have no idea where that is; still, always liked them. Obviously the sand temperature isn't an issue with them, though.
  
  There is no way that story is true right? How would that be any way better than a normal wide glass with a low center of gravity? Those would be rolling back and forth all over a rocking boat.
- If you want to put it down for a moment

Why would you put your beer in the sand? It'll get hot quickly.
- You also put water in the sand. As the water evaporates, the beer will grow a small beer-tree with 6-7 small beers you can harvest.
  
  hello, 911?
- The sand can be cold. (am I the only one who goes to the beach in winter?)
  
  Yep you are
- Hot beer tastes better, as long as you're drinking good beer.
  
  Are you British by any chance?
  
  Less of a good vs bad beer distinction, more of a light vs dark beer distinction I'd think?
  I want my pilsner cold, but porters and stouts are good warm.
  
  Hot beer?
  I've heard of warm beer being a thing in Europe, but never hot. That sounds foul.
  
  Found the bot

fun fact: people often go to the er from 'falling' onto objects like beer bottles and then getting them stuck, a friend of mine once sent me a picture of a closet in the hospital she works at that was filled with the objects people had 'fallen on'
- Is that some kind of trophy room?? Why are they keeping them???
  
  For the aroma.
  
  I guess so... We have a cabinet full of stuff people stuck up their urethra. They are cleaned and kept. I don't know why, maybe just for fun. And yeah it's fun to look at that.
- Stuff like this used to start wars like fr

Don't put glass bottles up your ass, they can break. PET bottles, preferrably filled with water if thin walled, are more recommended as a crude DIY solution, but still have their own issues, like lacking a base, and still can break.
- Whatever happened to putting a condom on produce? Cheap, infinite choice of shape and size and no sharp edges if it breaks

At least it's a bottle and not a jar
- Ahhh the old internet.
- Hands down, one of the weirdest quirks of the russian assholery in ukraine.

Doesn't the beer just get warm quickly in the sand?
- It gets warm in your hand too
- That's why this ER doc is trying to dissuade people apparently.

Don't fuckin' tell me what to do.
- Do not stick this bottle in your anus.

Why else would the tip be ribbed

I will not be suppressed.

Too late. And I'm not even that big on butt stuff!

A guy shoving a beer bottle up his ass is one of the things that precipitated the collapse of Yugoslavia

No one talking about the fact that the label says "Cream Blindness"??

at least the sharp edges of the bottle cap could dig in and therefore function as a sort of a base
- Apparently I'm that guy, but I definitely think it would just tear about 20 neat little grooves in one's rectum, and not do jack shit to prevent it being "lost"

Oh look at this guy lording over all the sand on the beach. I for one am an independent free thinker

Well too bad now I am definitely thinking about it.

that's brill! You can easily have WARM JAPANESE BEER.
What could possibly be better...

Instructions unclear, now my ass is stuck in the beach.
