Words above are associated with certain rude word for rear end used in American English which means also "donkey". If that word can mean both "donkey" and "rear end", why words for donkey would not have meant also "rear end"?
Mruism (Polish mruizm) - another name for anti-catholic heresy of monotheistic radical universalism (moraun, moraunism, MRU).
It's only coincidence that 'ass' the animal and 'arse' the body part ended up as homophones. Spelling the body part as 'ass' is just a phonetic spelling of 'arse' with a non-rhotic accent.
That's why other terms for related equines aren't typically use as synonyms for buttocks. There is one though,
hinny. A hinny is a donkey/horse hybrid, it's also used as a euphemism for 'ass' in the sense of one's back side.
