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...

one oh one 

A spare male at a party, or a useless person - always male.

Refers to the fact that in most countries on Earth, there are about 1.01 men for every 1 woman, thus, every one hundred and first male is not going to find a partner ( See www.nationmaster.com for confirmation ).

a:"NAME came to the party stag again?"
b:"Yes, our own little one oh one . . ."
