Thou shall not use the phrase "Bitch slap"

I went home last weekend to sleep in a bed that is bigger than a matchbox and eat food that isnt frozen. On the way home I heard my favourite conversation to date:

Blonde Kid: "I cant believe Sam's Mum said hes not allowed to listen to rap anymore."
Brunette Kid: "I know if my mum said that id well Bitchslap her."

And that kids is probably why Sam isnt allowed to listen to rap.
