Fox News and other news media have been calling the protests by the Tea party movement, "Teabagging parties." As Rachel Maddow says, "Apparently they didn't check Urbandictionary before they chose their name."

Teabagging

To have a man insert his scrotum into another person's mouth in the fashion of a teabag into a mug with an up/down (in/out) motion.
