Tea bagging is mostly used in two ways.
1. A sexual act where a males testicles are dipped in and out of the partners mouth. Similar to how a teabag is used while making a cup of tea.
2. A practical joke, where a male will place his testicles on a friends face and a photo be taken to embarrass the friend. Usually at a party when a friend has fallen asleep.
1. While giving me oral sex, Jess tea bagged my balls.
2. Did you see the photo of Rusty teabagging Rob after he passed out?
