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.
