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 common name for a 6.9 year old child who knows way too many swear words (such as fuck you, or, die you cunt!). He almost makes you question if he is actually a 69 year old pedophile who is targeting children in the Hypixel bedwars server. The squeaker also is 100% convinced that he is in a sexually intimate relationship with your mother. All in all, the squeaker is the most annoying gay-mers (gamers) on the planet.
The squeaker kept yelling: "I FUCKED UR MUM! I FUCKED UR MUM! SHE LIKED IT! SHE LIKED IT!"
