Bizatch slap 

To bitch slap someone, but in their butt instead of their face. Usually done to a woman, horse, or a very unhappy man.

I bizatch slapped myself and got turned on.

Bizatch slap 

When you slap your girlfriend so hard, her mother feels it, in fact, her grandmother feels it.

Matter of fact, her great great grandmother, once removed, feels it.

Yeah I hit my girlfriend. I gave her the ole bizatch slap.
