Uncle Buck

A guy (family friend or an uncle) who can playfully corrupt children's minds on what not to do, especially in public areas

My uncle buck taught me how to drive like a madman as in one of The Grateful Dead's song Casey Jones.

uncle charles

That dude who will lend you $350 to pay for your car insurance when you have misspent your pocket money irresponsibly, or lend you money when you’re in a pinch.

Damn... the car insurance company did me dirty. Imma call Uncle Charles and see what’s what. I’ll pay him back... eventually.

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 sauce

When you stick your uncle into a juicer and ejaculate into the juice produced by the juicer and feed it too your cat Mittens and he ejaculates while vomiting into a can.

I just love uncle sauce on a Monday morning.
