I rarely teabag, but when I do, it's out of respect. Had a recent match where I was the king of my crappy team and finished with something like 17 kills and 12 deaths. Of those 12 deaths, 10 of them were from this one guardian that finished with something like 35 kills. When I finally killed him for the first time near the end of the match, I just had to teabag him out of respect.
