Unwanted and irritating advertisements that pop up in a separate browser window, hence the name "popup". Only lame, computer-illiterate, Internet Explorer-using people get them.
IE user: These popups are so annoying! I can't do anything without getting a popup!

Firefox user: -Laughs-

Ads that "pop up" randomly on your computer screen while you browse the internet.
Pop-ups aren't that bad. Just get pop-up blocking software or X the ads out. Geez.

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.

I totally dislike Pop-ups!

A one time girl who comes about abruptly and wants to hook up with you. You have two options: you can exit the pop up (telling that girl hell no) or you can click on it (getting with the girl) and after leaving on the street like a piece of trash.
Bob: I was on facebook and there was this girl who kept talking to me.

Friend: Dude she is defiantly a pop up
