A guise for gay butt sex, a Tour de Keller is when two men tell everyone that they are going for a leisurely bike ride, but instead go behind the dumpster at a local Wendy's, and proceed to take turns fisting and pounding each others assholes. Their assholes be in obvious pain, but they can simply claim it was from the long bike ride.
Steve: hey man, you want to take a tour de Keller?
Patrick: yeah, I could use a good pounding, but need a good excuse to tell my wife why my underwear is blood stained.
