what's the word for a leg elbow?

You mean...your knee?
- ...oh
  
  Just how high are you?
  
  Higher than giraffe titties, huh?

Couldn't help myself.

- A shrubbery!
- ow, I hurt my Ekke Ekke Ekke Ekke Ptang Zoo Boing
  Yep, checks out 👍
  
  Goddamnit I even did the voice on my head as I read your post. Well done

The outside is the knee. The inside in the eenk.
And the bit on your arm opposite of the elbow is the woble.
- The loose bit of skin on the outside of the elbow is called the weenus
  
  Hey, Simpson. Your weenus is showing!
  
  I did not know that. Thank you.
- Jan, you're such a wenis.
  
  The wenis is a dance.
- I did not know that. Thank you
  
  Look at me. No, look at me. I need you to know that it's a joke. I spelled the words backwards.
  
  Congratulations, you're an gullible idiot!

Why, the kneepit of course!
- We don't call it the elbowpit, so this must be the legpit.
  
  No. Leg pit is the taint. The elbow has two sides.
  
  Armpit is where your arm attaches to your torso.
  Behind your elbow is a different pit
  
  I actually do call it the elbowpit

You mean the knee?
Don't feel too bad. One time I had a brain fart and couldn't remember the word "microwave" and called it the "nukeamajig." I still do, but on purpose now.

I would say "inside of the knee," if I'm reading the context right.
- Wouldn't the legpit be the pocket created at your hip when your leg is folded against your body?

Knee?

Do you mean the popliteal?

It's called "popliteal" in English, sometimes but uncommonly shortened to "poplit".
- There is also "hock", but that is mostly used in relation to horses.

Tell us you have ADHD without telling us.

This is what my uncle would call a "real knee-slapper"

what, your grunch?

Those orange and brown stripes remind me this Minecraft cat. Such a beautiful color.
- Nope, that's an orange/red tabby while op's is a calico, which is also present in Minecraft. Fun fact: except in rare exceptions all red tabbies are males and all calicos are female.
  Note: these aren't breeds, but names for the coat coloring.
  
  Your fun fact is only partially correct. Calicos and torties are almost always female because the black/brown/grey(dilute) and red/orange colors are both located on the X chromosome, so in order to have both colors, they have to have 2 X chromosomes. Male calicos & torties have some genetic abnormality such as XXY or are a chimera. Red/orange females are much less common than red/orange males, but not all that rare, because they have 2 X chromosomes and therefore have to have 2 copies of the red/orange gene to be solid red/orange, while males only have 1 X chromosome, so they only need 1 copy of the red/orange gene to be red/orange.
  Another fun fact: All domestic cats with red coats are tabbies. Through selective breeding, some reds exist with a coat that appears solid, but they're still tabbies with the agouti gene, just very low contrasting in the striping.
  
  yep! that pic doesn't really show off her coat very well
  
  this pic is from when I fell asleep on the couch and came up to bed and she was all snuggled up like a shrimp and was so snoozy she didn't wake up till after I layed down
  
  So, is this the right one? At least the colors match, but it doesn’t have any stripes.

Did we ever get an answer to this?
