I've seen quite a few people here get upset by what they consider to be "teabagging". It's not teabagging. When I crouch and stand repeatedly, mainly at the location of your death, I am engaging in celebratory crouching. It's a tradition of sorts in many multiplayer games, and I've seen it been done since the Halo 2 days. There's no ill will involved; it's merely a celebration of a kill I received and I want you to see it. That's it.
