An impolite and unghetto way to tell someone to shut their yap or they'll be stole in the jaw. Typically effective, yet more so when a 't' is added to the end. (Shut Up T)

Shut your mouth beau
You're supposed to be a PhD holder
Not a screw up stalking people and sitting on urban dictionary writing stupid definitions

What is your problem
You need a good fucking backhand slap to your face with my left foot
Don't waste your life Doc
Put your life to better use than being a cunt

S
Shut up and eat some fucking humblepie
