Ugandan Knuckles

A Meme created by this YouTuber, Stahlsby, called, "YOU DO NOT KNOW THE WAY", messing around with Gregzilla 's Knuckles Model.
It was originally used for "Knuckles Sings". (This meme is the shit.)
This used to be a random VRChat gameplay, but many 8-year old kids are spreading to show "de wae"; the sign of the end of the world.
Like what the fuck man? What is wrong with you, like holy shit.
It's spreading EVERYWHERE. YouTube , Roblox , scratch.mit.edu , here, etc. I bet it'll migrate into some News shit.
Thank the lord you survived this through

"Ugandan Knuckles succs dicc."

Knuckle Box

(N.) To be a royal screw up. To be the one to totally fuck things up for others and never be held accountable. To be a slacker and never get fired. One who is void of all intelligence to the point where breathing and blinking stress mental processing speeds.

(V.) Knuckle Boxing: The result of def: (N.). To screw everything up as a knucklebox would. Being unable to identify responsibilities and destroy all confidence in ability. To bitch up the works.

I can't believe B. Kieth knuckle boxed production again!

Bill, you knuckle box! Stop knuckle boxin this shit, BITCH!

Your bitch-ass knuckle box attitude is WEAK!
