Swishy Dog
A Swishy Dog is a prank to play on either a sleeping, drunk, or otherwise incapacitated person at a party or wherever the situation permits. Simply wait until the victim passes out, or is sleeping. Next, take a room temperature hot dog and insert it into the victims mouth. "Swish" the hot dog all around the inside of their mouth, teeth and gums, forcefully if needed to ensure that they will wake up. continue to slap it across their face and forehead until they open their eyes. Next, hide the hot dog, unzip your fly and pull your dick out of your pants and present it close to the victims face. If properly executed, the victim will suspect that they just got finished getting mouth raped and subsequently never be the asshole who passes out at a party again.
After falling asleep to an episode his favorite show, Harry Paratesties woke up abruptly to something forcing itself in and around his mouth emitting a salty taste throughout. As he opened his eyes he immediately was horrified at the large, uncut penis that swayed before him. A burst of laughter ensued as all of his friends accused him of blowing another man. But everyone at the party knew that he hadn't, he was just the victim of a perfectly executed Swishy Dog. (See also; felching for duckbutter)
