pop up 

a sexual game in which a group of guys and girls gather round and the men sit down with thier pants around their ankles. The women then can do anything to the men but touch their penis. The object is to see who "pops up" last. the women are competing to see who can turn the men on the quickest. Or you can play it reversed where the last guy to become aroused wins.

Hey everyone! Let's play pop up!

Pop up 

A phrase mostly used by teenage girls (but often by wannabe playboys) on social media platforms like Snapchat, when they want specific people to talk to them without them initiating the conversation. Usually to gain the attention of a crush or any hot piece of ass without making it obvious. Ironically it is so common and overused that to anyone with half a brain its as obvious as the night is dark.

pop up 

Karl's definition of pop up for experiment 2 of DESN285.

1.Annoying windows which seem to spontaneously appear while on the internet. Used by web companys to make money to pay for their website and to generally piss the common internet user off.

2.Pop up is also a much simpler way to explain abiogenesis (spontaneous generation), which is when a living thing or an object suddenly appears. Is the reverse of spontaneous combustion.

1."I hate using the internet these days, there are so many pop ups everywhere"

2."Shit!! look over there, that guy just popped up out of no where"
