Uncle Nephew

The incestious offspring of your grandmother and your brother, or your grandfather and your sister. Being the brother of your mother, and therefore your uncle, and the son of your sister, and therefore your nephew. He is your respectable Uncle Nephew, and he is quite a debauchery of gene mixing.

Good Ol' Leonard Bobby Ferguson was sitting on the top of Mount Rushmore one day when he saw his Grandmother wearing a very revealing outfit.

See, him and his Grandmother were only about twenty years apart due to the family tradition of giving birth at the age of ten. Leonard, who I'll refer to from now on as Leo, felt the old feelings rising in him again and brought his family to a new low by commiting an act of incest with his own grandmother, which she enjoyed just as much as he did...for fuck's sake.

Anyway, eight (not nine) months later their offspring was born. Leo's brother Siegfried reluctantly called this new family member his "Uncle Nephew."

Uncle Mung's Chunky Shrimp Buffet

A slang term popular in southern New England, used to describe the act of cunnilingus on an 'unclean' woman. This phrase is especially used within the context of women who are 'dirty' in terms of hygiene simply by choice, and care little for rectifying this issue.

"Yeah, so our friend was in the hospital for 2 weeks. He had 3 different infectious diseases, all of which were previously undiscovered to science."

"Holy crap! What did he do?"

"He had a reservation at Uncle Mung's Chunky Shrimp Buffet."

"Oh damn."

uncle leroy

All you need is two people and a victim. The first person holds the victim down and puts their feet up, then the second person comes in and punches the victim square in the butthole. It hurts like hell. Preferably done to the 5th grader who lives across the street that tells on you all the time. One day he'll learn.

Dude we held down jimmy last night and gave him an Uncle Leroy and he cried like a bitch.

Shut up or you're getting a straight shot to your pooper...uncle leroy style!

I tried giving my wife the Uncle Leroy last night for not washing the dishes.

Uncle Dude

A guy that tells his wife/girlfriend about the exploits of his friends, thus getting his friends in trouble with their wives/girlfriends. Usually done preemptively to try to maintain innocence.

Jerry is such an uncle dude, he told his wife we went to a massage parlor and she told my wife.
