When a girl lays on her back with her mouth wide open and you drop your balls in her mouth.
You'll never believe what I did to that girl from the club last night...I tea-bagged her!!!
When one person has their nuts in another person mouth.
They call this T-bagging because it's like you do a tea bag up and down.
The act of
1. pwning a noob
2. standing over his lifeless body
3. and crouching many times over his head in the ultimate show of disrespect.
GUY 1: "d00d guess what i did?"
GUY 2: "what?"
GUY 1: "in Halo, I pwned a n00b, and t-bagged him!"
GUY 2: "OUCH! t-bagging can kill a mans pride!"
when you put your balls in the mouth of someone who is sleeping and take a picture as a joke
when you place your balls on a random punters forehead and take many a picture of it
The act of hanging a t-bag, preferably a used one, on a tree branch.
I was walking behind this guy on the way to class when I saw him t-bagging on the sidewalk.
