You might be confused as a learner of English by the many idioms that include the word “ass”. I have already mentioned in a previous entry “pain in the ass”, but the ass idiom is so much more.
Of course, ass can be an animal. But we seldom use the word since the other meanings overpower it (kind of like using gay for anything besides homosexual.) So, besides the four-legged horsey type animal let me remind you that ass is a casual term for that area between your lower back and thighs. It’s what you sit on. So, how do Americans use ass?
Well, if you tell too many jokes, and especially if you are sarcastic, someone might call you a “smart ass.” If you do something stupid, you are a “dumb ass.” Overweight? fat ass? Inactive? lazy ass. I think you are starting to get the picture.
Also, someone might refer to your ass. For example, if they want you to move quickly, they might say “Get your lazy ass out of that bed.” If they won you at something, they might say they beat your ass.
The list goes on and on.
Have any other ass idioms? Let me know.
