The creepy act of getting into a relationship with a "step" or distant member of your family, such as a stepchild, second cousin, or "stepcousin". This type of behavior is not illegal, but definitely creepy. Named after Woody Allen, who married his ex girlfriend's adopted child. (Arguably if not definitely his stepchild.)
Mark: Hey I wanna hook up with Sarah, she's my uncle's stepchild, but that doesn't make us biologically family!
Joe: That's Woody Allen Incest! And fucking disgusting. Even though I'd plow her hard.
