This is rumored to be about oral sex, but it isn't. It is about a man who had to work with the band on a T-Shirt design. He either had a pierced tongue or a wart on his tongue and he gave the band a really hard time.
During the chorus, lead singer Jon Davis shouts a lot of unintelligible things. He claims it is just gibberish, but many fans believe there are actual words being said. (thanks, Nick - Paramus, NJ, for above 2)
