More recently, news anchors and bloggers have giggled knowingly over that sexual reference, but nobody has acknowledged how the word first entered popular American slang.I'll tell you how. John Waters.Here is the email exchange:XENI: Dear Mister John Waters: We at Boing Boing are devoted fans of your work, and we consider you one of the greatest heroes of the "happy mutant" culture we celebrate. Where does the term "teabagging" come from? Is it true that the term was first popularized, or originated, in one of your films? Also, what is the deal with right wing nutbags (if you'll pardon that term, too) appropriating a perfectly good term for a sex act in such an offensive manner? Your humble devotée.JOHN WATERS: "Teabagging" is by my definition the act of dragging your testicles across your partner's forehead. In the UK it is dipping your testicles in your partner's mouth. I didn't invent the term or the act but DID introduce it to film in my movie Pecker. "Teabagging" was a popular dance step that male go-go boys did to their customers for tips at The Atlantis, a now defunct bar in Baltimore. Hope this helps.
