A person on any type of online gaming voice chat, whose voice is really high, resulting from not going through puberty yet, or their voice cracking alot. Typically ages 6-14. (yes, 6 year olds play COD)

Squeaker: *high voice* God dammit! Why did you kill me? Normal person: Go to hell, squeaker shit. Squeaker has left the game.

For some reason this person thinks that they put fear into the minds of others, even though in reality they just make people laugh so much that their sides hurt. A squeaker is also the thing in rubber ducks that makes them go squeak squeak because that is exactly what they sound like. I kid you not, there is no difference between the two noises. When an attempt to tell you off is put forth, it is physically impossible to not laugh in their face, and it pains a person to hold in their laughter. I'm talking to you T-Bob. Just kidding I don't know a T-Bob.

As the squeaker told off Luke, every single person the room was in pain whilst trying to hold in their cackling.
