(4 guys are passing two fat blunts around, you take a huge drag out of the 1st blunt and burns your throat, then right after the 2nd blunt is passed to you)
Jeff - "shit dude...i've just got snacks on snacks"
Brian - "rofl"
(In Seoul there are many motels next to bars...Guy walks out of the bar with a random hot chick he picked up at the bar and heads over to the nearest motel.)
Guy - "damn...snacks on snacks right here"
