When you are in a bad mood and frustrated you go bitchbashing which is nothing but beating whores up at night. After that you feel relaxed and go home in peace.

B: Me, too. So, what's the plan for tonight?
A: I'm going to do some bitchbashing! Wanna join?
B: Hell yeah, let's beat those whores up real bad!
