Knuckles is the game much like slapsies, but much more betterer. You play by having two players facing each other, each one with one clenched fist touching the other persons clenched fist. The person who takes their go first tries to hit the top of the other persons hand with their knuckles. If the persons succeeds, they get another go. They keep going until the other player manages to remove their hand without any contact being made from the opponents ATTACK. Then its the other players go. IF the recieving player tries to dodge THREE TIMES without the attacker actually having a swipe, then the attacker gets a free shot (i.e., the reciever has to hold their fist out and take a blow without moving).You carry on until one person quits. Some people have the rule that when someone quits, they have to take a free forfeit blow, but this is sometimes dangerous and i dont think a very professional way to end the match. Maybe a handshake or something. If you havent heard about the game, please spread the word! I'm trying to get it as well known as possible, because im really fucking good at it and its the only thing im good at. :D! Happy Knuckling.

A game where a group of people sit around a table with a coin, preferably £1, but most/any will work. One player spins it for the person on their left to catch between their index and middle fingers. Play moves in a clockwise direction. If the spinner mis-spins it 3 times, the catcher slides it along the table very quickly at their knuckles. This also happens if the catcher catches it with the coin horizontal. This happens in reverse if the catcher mis-catches it (once).
We played knuckles in school today, and people were wondering why our knuckles were all mashed up.

A fight or other violent skirmish between at least two punters. Often alcohol related or occurs in a pub. To 'go the knuckle' is to punch on.

When a quality nugget is so densely dank that it makes a noise identical to that of someone's knuckle when it is tapped on a surface.
I just dropped some serious bills on that zip so those buds had best knuckle.
