It's a sign of maturity, or lack thereof. I can't imagine that an actual adult would get off on this type of juvenile behavior in a video game played by people of all ages. I can't see a mature adult getting off tea bagging other adults and I can't see an adult getting off tea bagging 12 year old kids, because that seems kind of pathetic to me. So I have to conclude that the only people who tea bag are immature morons who still have a lot of growing up to do. Knowing that to be true, nobody should allow the actions of a moron to affect their mood or enjoyment of the game. If you get tea bagged, simply look at the screen, mutter 'poor moron' to the offender, and play on unaffected. Letting them rile you empowers them. Don't take the bait. They're just idiots. One day they will grow out of it.
