They are stupid advertisements. Sometimes they contain viruses, adware and spyware and you can't avoid it like e-mail.
They give you viruses and spyware without warning.

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"

An internet advertisement that comes in a separate window without warning and without your consent. Some look like the operating system's buttons and asks if you want to scan for popups, which tempts less smarter people to click them which will run an ActiveX control which will install more popups.
A popup ad is like a vacuum cleaner salesman that comes to your door at 1:30 in the morning and dumps ashes on your carpet, then won't pick it up until you buy their vacuum cleaner and pick it up yourself. Meanwhile, the vacuum cleaner is loaded with viruses in the bag and you get sick.

Stupid little windows that are supposedly "blocked" by your damn pop up blocker. These are usually advertisments for gay ass things like music that costs you your soul and things like that. They might even have sound.Sometimes they even advertise mexican porno and up comes a fucking picture of two people having sex with each other. EEEEEEWWWWW! Popups are the scourge of the earth.
I think i will look up spongebob for my little sister who is only four and if she were to see something like a popup showing something nasty her little mind would be warped forever. OOOOOOOOOOOOOOOOHHHHHHHHH PACO!!!! AHHHHHH! cover your eyes booboo it's the popup monster!!!!
