A person, usually using a chat feature in an online game, who is young enough for their voice not to have deepened. This makes it high-pitched and unbearable to listen to. Squeakers usually use long streams of invective to make their point clear.
(Squeaker gets killed, trolled, and otherwise annoyed) Squeaker: What the fuck you fucking asshole you're cheating you're using a fucking hack I'm going to fucking report you you fucking piece of shit.

(Squeaker scores a minor victory) Squeaker: I'm the best player in the world suck my balls you fucktard... You get the idea.

A child on XBox Live approximately 7-12 yrs old, who has a vocal pitch which is not only annoying, but painful to all who have to endure it.
I hate it when Dave's little brother gets on his XBOX. That little fucker pisses me off. I'm not going to let Dave join our parties anymore if that squeaker signs on as him one more time.

A squeaker is a child that has not reached puberty who plays a game and used a mic to talk on it, often then not people use the term squeaker for all children that play online with a mic, which is somewhat true, but squeaker is actually for something else.

A squeaker is supposed to be a child who has a mic and constantly screams, trash talk, and/or swears alot, often then not, they tend to have very low anger control and get mad easily, often then not people like making them mad, they also are often horrible at the game and may rage quit.

There's also another "Squeaker" that can be good at the game (can be decent or bad) and have less of a shortfuse, they also can friendly to others and be less of a annoying shitstain, they still have high pitched voices but usually they try not to have such a loud mic, often then not people still make fun of these squeakers despite them doing nothing to be a piece of shit, many people do this because the voice is either too loud in the mic or annoying, which the latter they cannot change.
Squeaker: "Oh mwy fwucking gwod fwucking of fwuck ywou fwucking twuh swhit of twuh dwam*improper swearing usage*"
Game Player: "Oh my god shut the fuck up!"

And then

'Squeaker': "Hi, how are you guys?*or another example that's not annoying*" With a not loud mic
Dumbass: "Oh my god shut up you stupid fetus, you're supposed to be the womb you fucking bitch, wait until your balls dropped you dumb child!"
