One Up

A marijuana smoking game in which you pass the spliff around a group and each person takes one more toke than the last. This goes on till there are not enough tokes left in the spliff for the next set of tokes.
Jeff - Lets play one up! I'll start: *holds up hand with 1 finger raised and takes a toke*

Jim - *takes two tokes and holds up 2 fingers*

Emma - *takes three tokes and holds up three fingers*

Jeff - *takes four tokes and holds up four fingers*

Jim - *takes five tokes and holds up five fingers*

Emma - *takes six tokes and runs out of fingers*

and so on...
