What's on your mug?

A person over an online game with microphones who has an annoyingly high pitched voice, often under 11. Squeakers commonly get upset over every bad thing that happens to them, taking it out on fellow players through loud shouting and mass amounts of swearing and name calling. Commonly found in popular FPS (first person shooter) games ex. Halo 3, Call of Duty 4, Battlefield 2 etc.

squeaker:"Dude you guys suck! You got me killed because you didn't sacrifice your own life for mine! I kicked ass in the beta! You all are such n00bs, you would never make it in my clan." guy 1:"Shut up you squeaker."

A kid that hasn't reached puberty yet, This child is most likely under twelve (12). This child swears a lot because (most likely) he thinks it makes him cool. Squeakers normally have a very short temper and they either put the microphone too close to their mouth or they just scream their little heads off when something doesn't go their way. Some Squeakers will talk about sex a little bit too much (meaning a lot).

Squeaker That Doesn't Get His Way: *Screaming* YOU FUCKING KILLED ME YOU FUCKING FAGGOT I WILL FUCKING KILL YOU YOU LITTLE SHIT! HACKER! MY DAD WORKS FOR THE GOVERNMENT SO HE WILL FIND YOU AND KILL YOU YOU FUCKING IDIOT! I WILL FUCK YOU AND YOUR GIRLFRIEND YOU FAGGOT!

A gamer on voice chat that has not hit puberty or has an abnormally high-pitched voice. They will often use a rediculous amount of profanity to try and offset their lack of audible maturity.

Dude, that squeaker on WoW gave me a really bad headache!

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.
