Uncle Guido

The protectorate of Italian hoods back in the day, undoubtedly affiliated with the Mafia. The guy who comes in the middle of the night to carry out unethical deeds.

"I ain't scared o' those Tony's."
"Wisen up, you don't want a visit from Uncle Guido, do you?"

Uncle Googemizer

A sexual act in which a man freezes his excrement in a common household freezer for 8-10 hours. Afterwards, it is then taken out of the freezer, at which point the female uses it to masturbate. For maximum pleasure, it can be frozen along with the female's excrement and frozen for 24 hours.
Afterwards, both male and female simultaneously use it as a dildo, ass-to-ass or ass-to-vagina. The objective in this sexual 'game' is for the male and the female to ejaculate or cum, respectively, before the excrement starts to melt.

Man: Honey, I'm so bored of our lovemaking. Perhaps we should try something new?
Woman: I've heard about something called an Uncle Googemizer. Perhaps we should try it?

- 1 day later -

Man: Wow, that felt so great! We should do it again.
Woman: Indeed, but we must remember to buy more laxatives.

Uncle Glenn

A seasoned man with a militant approach to Recovery. Just the sound of his voice has been known to increase the chance of long term sobriety. Although he may look like Uncle Fester, the ladies in Recovery flock to him like flies on poop. He is idolized by the recovery community and is often referred to as El Heffa.

I thought I knew about Recovery until I met Uncle Glenn and realized I didn’t know shit!

Uncle Grubby's Special

While in midair (from a jump for example) you fart on your hand and slap the fuck out of someone next to you (generally the back of the head or the face.)

Jarome: "Can you believe it, that bitch didn't want to deepthroat me?"
Tim: "What did you do about it?"
Jarome: "I kept giving her Uncle Grubby's Specials until she did what I said."
Time: "Yeah thats what I would have done too."

Uncle Google

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.

"I didn't know much about the Second World War, so I asked Uncle Google and he told me where to look"
