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.

Get the Woody Allen Incest mug.
When your big fat aunt named Allen becomes insanely obsessed with spying on her Nephew and his wife, as they perform the amazing piss tornado twice a day . Sometimes she puffs out her boobs and grunts after belching a load of dog jizz down her chin like its an act of dominance, AWWW Bless her lil heart she's got the IQ of a wolf rat banned from the city.
Daughter: Hey MOM Look at that disgusting fat sperm whale taking a shit in the pool.
Mom: Thats Incest Allen your Aunt, wait till you see her pissed off drunk on a bass boat with no Rottweiler jizz to drink.
Daughter : Gross . Ill never eat hot dogs again.. MOM She scares me..Can we go skate park instead?
