ugandan knuckles

A popular meme starting in January 2018 involving a chance experience caught on the popular game "VR Chat" in which a man's voice comes through a badly 3d modeled tiny knuckles character asking the pivotal question,"Do you know Dr Wey?"

I just found another Ugandan Knuckles meme and I still don't get it.

Pig knuckle

When you cross your index and middle finger, then your pinky and ring finger. Then insert two in the pink and two in the stink.

Last night I pig knuckled my wife.

knuckle-off

The act of ejaculation or masturbation. Rooted from the trifecta of knuckles that surrounds the end of a penis during masturbation.

"Hey man I'll be over in like 5. Just gotta go knuckle-off a few."

"That girl was such a tease, but whatever. I'll just knuckle-off a few when I get home."

Sponge Knuckle

Close to the idea of a moose knuckle or a camel toe. The only difference is that the woman is really fat and she wears tight pants and you can see the cellulite through them, looking very similar to a sponge.

I was walking down main on a Friday night. Bitch had white yoga pants on and you could totally see her sponge knuckle.
