Friendship Incest Syndrome (FIS)

Friendship Incest Syndrome is an occurrence where you have a group of friends who have all dated and broken up with the same people, then you are eventually forced to be friends with an ex because they're still in your circle of friends - in fact they're probably dating one of your friends by now. It effects a small # of people, likely living in Southern California. It extends to Frenemies who have removed themselves from the circle whom you can never fully get away from.

Incest Allen

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?

Incest

Yes. It's incest. Is your husband's parents... Also YOUR parents? Yes. Daughter in law and spirit.

Hym "Incest. And there is a bell curve of acceptable death where it is relatively more fine for children and the old to die than the mid aged. Additionally, what makes children innocent? If the lie, hit, kick, and steal more than adults... How are they somehow MORE INNOCENT? It's their relationship to pleasure. And God both murders kids and tells people to murder kids. God loves it and so do it! Yay! Child Murder!"
