Squeaker - Child video-gamer who uses the mic. Usually refers to children who play
first-person shooters, esp. the Call of Duty series.

The age range of squeakers is approximately 4-12 years old. Squeakers tend to
have extremely high-pitched voices and use the mic heavily in foolish and annoying
ways.

Usually, the younger the squeaker, the more ridiculous amounts of profanity they will
use.

You fucking motherfucker! Stop fucking using the fucking MP7 on fucking CoD! Imma fuck your
mom, you piece of cock-sucking faggot piece of shit!

11-year old:
Dammit, stop camping, you fuckin' camper!

Preteen to midteen aged girls who flock together in malls and at social events.

Term also applies to the noises these girls make, especially when they are startled or excited.

Such groups are called squaggles, as in a squaggle of squeaks. Their male counterparts group in gaggles, as in a gaggle of geeks.
I like going to middle school basketball games just to watch all the cute little squeakers who get so exicted watching the game while simultaneously trying to remain cool.

Even though he pulled hard on the sides of the chair and lifted his feet, the fart blew out as a long, loud, squeaker, dashing any hopes of a second date with her.
