Rachel Maddow is just giddy with the depraved sexual connotation associated with that term.
Ummm pretty sure Maddow is into other women, like the type you see associated with Code Pink.
I would imagine she either has never been teabagged or is the teabagger not sure
OK for those of us who have been living in a cave what is so funny about that term (and which term are we talking about?)
