You think what we teabag is a corpse? It is not a corpse. If that is a corpse then you need to stop killing thousands of people/aliens. It is a game, treat it as such. Also, what lacks in the real sports that lacks here. I'll give you a hint, verbal communication. Yes, you can generally talk with your team, but usually cannot hear your opponents. NFL players taunt, tease, bash the other team to get on there nerves, to get them riled up. We can't do that, so we switch it to non-verbal communication. If tea-bagging was so disrespectful, why was it intentionally put in Halo 4? I mean, developers are disagreeing with you. Is it disrespectful to dance over a Fallen Captain's corpse? Why is it considered 'excessive celebration" in one circumstance, if not the other. In fact, I would consider it excessive celebration when doing it to the Captain, because he is easier to take down, there fore less effort went into equally celebrating.
