Jager Main 

A deluxe piece of cancer that gets head shot at the begin of each defense round attempting to spawn peak and cries him or her self to sleep every night for the acog.

A toxic piece of shit who ruins the fucking game and doesn't let anyone in the building because they are all dead by the time the timer hasn't even hit thirty seconds in the round. (Due to spawn peaking)

Player one: Fuck you Jager Main!You toxic piece of shit all you fucking do is spawn peak!

Jager: Get spawn peaked. Ha Ha Ha!
