I dont teabag for simply 2 reasons: its a waste of time, and Im not a necrophiliac.
I dont really feel like celibrating and gloating over one kill, while being vurnerable in the match. Im not the best sniper, but Im waiting for that day where I snipe someone who just happenes to be in the process of teabagging. Then n00blets will complain how I me sniping them during their victory hump was unfair because I caught them off guard.
