A line from The Hangover which has become a commonly used slogan by the movie's fans. The line is spoken by Zach Galifianakis' character when he uses the baby's arm to pantomime masturbation. The phrase need not be used in context; it possesses a non-sequitur, esoteric quality similar to "Free Bird!"
Joe: I'm so sick of my parents fighting all the time.
