"Dude did you know that Dead Space 3 has a co-op campaign"

"Yeah bro that Copaign is gonna be great"

There is a cop and a stop sign nearby.

DUDE! You better stop! COPSIGN! Dude, if you had stopped at that sign the cop totally wouldn't have given you a ticket.

Kirk Copain

A shot used for punishment, made of a shot of baileys, Pernod, lime cordial and some Tabasco sauce... The punishee must pay for the shot effectively loading the gun and shooting themselves. It tastes of curdled Pernod and Tabasco.

Oh shit, Curtis broke the rules again, that'll be another Kirk Copain
