A group of conservatives who attend a rally to teabag each other. The conservatives are usually old, fat white guys who are closet homosexuals. They often carry signs at the rallies about things that they don't understand like socialism, taxation, and healthcare.
Sometimes they perform the homosexual acts for religious purposes as evidenced by a sign at one of the Tea Parties that read "I teabag for Jesus!"
Billy Bob and Cheney left the slaughterhouse to attend a Tea Party so they could teabag each other without their wives finding out about it.
