Double uncle

(n) A double uncle is man who is someone's mother's brother and also that person's father's brother. In other words, a double uncle is an uncle on both sides of the family. For a double uncle to exist, a child must be a product of incest between two siblings, and the parents must share a brother.
Tyrion Lannister from A Song of Ice and Fire / Game of Thrones is probably the most well known double uncle. His double nephews don't appreciate him like a double uncle should be appreciated.

Person A: Dude, Tyrion is freaking awesome. He's probably my favourite character at the moment.

Person B: Yeah, it's a shame he's that Joffrey faggot's double uncle.

-----

Person A: My double uncle said he'd get us all ice creams!

Person B: Double uncles are the greatest!

Double Uncle: Now get back in my van, kids. And don't scream.
