some mcr fans (aka killjoys) may say this at times when someone says these things:
A:(normal sentence containing the words "you better")
killjoy: YOU BETTER STAY ON THAT SIDE OF THE STREET MF I'LL KNOCK YOU OUT!
OR
A: (normal sentence containing the words "that side of the street" or "that side/street")
killjoy:YOU BETTER STAY ON THAT SIDE OF THE STREET MF I'LL KNOCK YOU OUT!

A: and i was like, "bro stop stay on that side of the street! I need to catch up"
Killjoy: YOU BETTER STAY ON THAT SIDE OF THE STREET MOTHERFUCKER I'LL KNOCK YOU OUT!
