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"

A girl who fools you to feed your rubbish lifestyle. She uses you as her free time toy to distress. She makes you feel she is so into you to help your sick ego. Oh what a pop up she is.

One person : Oh she is soo into you!

Another smart person: You are just her toy, she is way above your catch.

You: oh what a pop up she is.
smart-pop up, like to confuse pop up, help the sick like you pop up
