Get the knucklemug. 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.
Ben: Are colin and adam knuckling with that guy over there?
Sean: Yeah that dudes dick is gonna be super sore wow.

Get the Knucklingmug. Any friend that assists you in your endeavors, or that you assist in theirs. A knuckle is of equal standing and not be confused with a minion, even though they may let you take the lead in situations where they are assisting you, just as you let them take the lead when you are assisting them.
Some of my knuckles came over last night and we gave the car a tune up and put in new speakers.
I burned my songs onto a mix cd for one of my knuckles.
One of my knuckles found a generator for next weekend.

Get the Knucklemug. 
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.
