Knuckling is the act of 2 bros fist bumping eachother. As the two bros fist bump eachother, a third bro proceeds to slide his dick between the other bros touching knuckles. He then proceeds to fuck their knuckles.

Sean: Yeah that dudes dick is gonna be super sore wow.

Get the Knuckling neck gaiter and mug.
Unlike Sonic he doesn't chuckle, he'd rather flex his muscles
Here I come, rougher than the rest of them
The best of them, tougher than leather
You can call me Knuckles, unlike Sonic I don't chuckle
I'd rather flex my muscles
I'm hard as nails, it ain't hard to tell
I break 'em down whether they're solid or frail
Unlike the rest I'm independent since my first breath
First test, feel the right, than the worst's left
Born on an island in the heavens
The blood of my ancestors flows inside me
My duty is to save the flower
From evil deterioration
I will be the one to set your heart free, true
Cleanse yourself of them evil spirits that's in you
Streaking lights, loud sounds, and instincts
Are the elements that keep me going
I am fighting my own mission
Nothing's gonna stand in my way
I will be the one to set your heart free, true
Cleanse yourself of them evil spirits that's in you
Won't be frightened, I'll stand up to all the pain and turmoil
Just believe in myself, won't rely on others
Get this power to wipe out the havoc and anarchy
This is my planet, gonna fight for my destiny

Get the Knuckles neck gaiter and mug.
A glorious meme. From a golden age of SEGA. When sonic the hedgehog 3 came out, sonic and knuckles was supposed to be with the game, combined into one.

But due to hard ware they couldn't, but with a special game of sonic and knuckles, you could combine them and get Sonic 3 & Knuckles. Thus years later sparking a meme.
I really like this game of Sonic green hill paradise part 3 .exe rise of lyric & Knuckles.

Knuckled on is the act of brown nosing with a boss or someone else of importance. It gets its meaning from the act of gripping someones dick. In extreme cases it is known as "knuckled on with both hands" denoting desperation in the act.
Look at the new guy! He's knuckled on to the foreman!

How did he get away with that screw up? He knuckled on with both hands and blew his way out of it.
