getting a surprise fuck in the ass. The art of screwing someone from behind, usually without them knowing that it is going to happen.

When a male is having normal sex with a female and he all of a sudden switches holes, to the butt.
I was with my boyfriend the other day and he pulled an 'azza' on me.
I tried an 'azza' on my gf last night and she got into it.
