Well if you HAVE to know, BhT's use of "teabagger" is a (derogatory) play on the phrase "tea party [attendee]", using the meaning of "teabag" defined by:
http://www.urbandictionary.com/define.php?term=teabag
- To dunk ones scrotum into the open mouth of another person
- Dipping your testicles into the open mouth of another person. Kind of like dipping a tea bag in and out of a cup of water.
- when a guy puts his balls in someones mouth.
Feel better now?
.....Hmmm....maybe I should give it a go?......is this a required practice before, during or after the party?
