killer 

A game you play with a joint or any other marijuana smoking device.
You take a hit and pass it to the next person who does the same, you have to hold in the smoke until the joint gets back to you.
This gets harder if there are more people in the circle
A variation is progressive Killer this is when you increase the amount of hits each time the J goes round the circle

"Yo Niall, rich you up for killer?"
"progressive or normal?"
"progressive man, were hardcore!"
