Uncles Knuckles 

1.When you uncle fists you and your sibling at the same time.

2. When your uncle literally punches your ass hole into the next dimension.

Uncle Knuckles 

For a female, Uncle Knuckles is the act of allowing an older male, preferably 10-20 years older than herself, to finger bang her pussy.

Hey Donna. What's the matter? You seem like you are day dreaming. Oh I am. I went to a bar last night and had me an Uncle Knuckles. How was it? He said it was finger licking good.
