A Jack-o-lantern, carved and left by someone's front porch, that is subsequently opened and defecated in by passers-by sometime around the Hallowe'en season. This prank was notably featured on Robot Chicken, but has been performed in various other circumstances. More than simply smashing pumpkins, giving someone a crap-o-lantern is considered one of the most profane Hallowe'en pranks in existence.
Honey, I just went out to the porch, and the neighborhood hooligans turned our jack-o-lantern into more of a CRAP-o-lantern.
