I bag when I'm against a sniper and I kill him by bobbing and weaving and just better gun play. Especially if there are two sniping me, and I get the double. I bag if someone keeps rushing me with a shotgun over and over again. I bag when I wipe the team with my super. I bag when I kill someone with hazard duty. I bag when I shutdown someone's super. And I bag when I get a kill when there are 3 or more enemies around me and I know I'm going to die. Just to piss people off.
