something i happen to accidentally grab every time i walk by a hot girl.

Originally just the name for the donkey, this word had no filthy connotations until about the late 1700s, early 1800s, when the pronunciation of true (English) word for the backside, "arse", had changed enough to sound much like "ass", seeing as how the English often don't pronounce the "r" when they speak.

To avoid any unwanted baggage associated with the word, the name of the ass was changed to "donkey". As a result, the word "arse" has disappeared from American vocabulary.

Although before World War I they were similar, the British pronunciations of "ass" /æs/ and "arse" /ɑːs/ are now very different.

The booty. Preferably a good one

word inserted between an adjective and a noun for seemingly no reason at all

'for that ass' means 'for you' (just another way of saying it). It has nothing to do with the actual body part, it just means I'm giving you something.

When a person cannot be bothered doing a task that is given to them. It is used when someone wants to remind on there backside/bum/ass. Hence the expression "Be assed"

Most of the time it is used in Liverpool, England.

A part of your body that has most of all chances to be kicked.
