I usually just stand right on their corpse and reload quick, looking right at their orb, then move on. Granted, I don't do this when the areas full of enemies, usually just with the one player that's sniping/camping. It's a feeling of "Yeah, I know what you're doing. I ain't having any of that bullsh*t, scrub." Most of the time I just keep going. I only teabag someone if they teabagged me first, and it's at that point I focus only on that player and proceed to destroy him the whole match, regardless of if we win or lose. It's more for lolz than anything, really.
