A French-American guy (grew up in US) in my school described an encounter at a zoo when he was a young. Apparently, he ran up to the exhibit and shouted, "look! it's a daddy fuck and a mommy fuck with a baby fuck!", much to the chagrin of his parents.
Presumably using full English grammar and such it would be: "Matka foka" for mother seal. I'm gonna go out on a limb and say thats probably not how its translated properly fully in polish. But I was really hoping mother would be mama in polish so it could be mama fucker!
