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.

Get the incestfulmug. 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!"
