Knuckles The Echidna 

knuckles is a loner, maybe it is because his father leaved him alone at the age of nine and his mother runed away...but, still i have my doubts

" bye son, me and your mother are going to have another child so...take care of yourself"
knuckles: daddy! oh, who cares?

Brass Knuckles 

Basically a four fingered ring. One of the best hand combat weapons ever invented. Used in the proper way can leave an opponent unconscious or possibly dead. They usually come in Brass, steel, Pewter, and copper.

In london they call brass knuckles Knuckle Dusters.

In Japan they call them Tekko with a slightlly different design.

jizz knuckles

Jizz on the knuckles. Usually happens when you decide to still squeeze one off when you don't have anything to catch your load in handy. Also a person who accidentally picks up a used condom thinking it was a ballon.

Yo, tuttle, thats not a balloon you just picked off the ground jizz knuckles!
