Usage
What does -ass mean? The combining form -ass is used like a suffix meaning “ass,” in the sense of "buttocks." While occasionally -ass is meant literally or to mean "(stupid) person," more often it is used as an intensifier. Intensifiers are words or word elements that essentially mean "very" or "somewhat." The form -ass is often used in slang terms, especially vulgar or insulting ones. The form -ass comes from Old English assa, meaning “ass,” in the sense of "donkey."Unlike some other combining forms, -ass is often separated with a hyphen, as in big-ass.

Etymology
Origin of ass1
First recorded before 1000; Middle English asse, Old English assa, probably a pet name or diminutive form based on a Celtic form, e.g., Old Irish asan, Old Welsh asen, from Latin asinus; akin to Greek ónos “ass,” from a non-Indo-European language of Asia Minor, e.g., Sumerian anše “ass”
Origin of ass2
First recorded in 1860–65; variant of arse, with loss of r before s, as in passel, cuss, etc.; see origin at arse
Explanation
Literally, your ass is your buttocks. In slang, an ass is a jerk or an idiot. Neither is highly regarded. When people are being slangy or folksy, you hear this word a lot: "Get off your ass!" "Watch your ass!" "Why are you such an ass?" "Get your ass in here." Though this isn't one of the very worst swear words, it is considered harsher than butt and lots of people consider ass to be an inappropriate word. You would be a lot better off using softer words like bottom or tush in most situations. Sometimes ass can also mean sex — another use worth avoiding.
