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.

Uncle Google is like that scary older relative that your mum warns you about hanging around with, but you do anyway because he knows almost everything; and he can always be relied upon to show you some puppies. Unfortunately he also makes you look at dirty pictures too, whether you want to or not.

When your uncle pays you a special visit during the night and latches hold of your cock like Harambe and gives you a tug job so hard you think your dick is going to get ripped off.

When you spend the night at your cousin’s house and you wake up in the middle of the night being aggressively spooned by your uncle with a little something stiff knocking on your back door.
