What is buttock? How to use in English

The word "buttock" has its roots in Old French, where it was spelled "botoc" or "botoke". This term was derived from the Latin word "but Bacca", which referred to a buttock or haunch of meat. The Latin term was likely imitative of the sound of a joint creaking or cracking, which made sense given the association with a cut of meat. The Old French word "botoc" was later borrowed into Middle English as "buttock", initially referring to the rear of an animal. Over time, the term's meaning expanded to include the human backside, with the first recorded use of this sense dating back to the 14th century. Today, "buttock" is a common word used to refer to the buttocks or hips.
