means to have your ass smashes hard, to have extremely rough aggressive anal sex, usually only tramp stamp type girls are okay with a total anal smashing doggy style because they know there pussy already no good no more.
I met a girl with a tramp stamp at the bar last night and she told me to give her a good hard anal smashing.

Yea I was going to anal smash my girl friend on my birthday, although, I cheated on her and never got the allusive anal smash.
