The natural act of a man dipping his ball sack into either a woman's or defeated opponents mouth as if it were a Tea-bag.
Most often used in the gaming community as a victory move. After you kill an opponent you highly dislike it is not uncommon to stand over your enemies lifeless body and crouch up and down over and over in a T-bagging manner while the opponent watches from the kill cam his body being defiled. (Note: Although uncommon T-Bagging a player while in a laying position such as sniping can also be done and is extra funny for the kill cam review.) Note that T-Bagging can get you spawn killed or verbally assaulted over the microphone.
"The gamer finally killed his opponent after many spawn kills and took his revenge by T-bagging the body of his downed opponent."
"Did you see that asshole? He just T-Bagged my body! Everyone spawn kill him!"
T-bagging is an ancient ritual that originated on the Xbox exclusive title Halo. Tea-bagging is a term that refers to the action of repeatedly pressing the crouch button on the bodies of your dead enemies (or teammates depending on the situation) to mimic the action of rubbing your balls on their face. The goal of T-bagging is usually to entice anger and frustration in the victim in the hopes that they play worse and make mistakes. T-bagging can also be used as a friendly gesture, when T-bagging an alive opponent you symbolize peace and friendship and if the other player returns your T-bag, an unbreakable bond of ball bouncing brotherhood has been formed.
