knucklebug 

An odd mysterious bug that you only see on your knuckle and no where else. You then interrupt your friend’s conversation about some bomb ass booty they saw in the gym, telling them about some bug on your knuckle.

Hey! Did ya’ll see that knucklebug on me?

knucklefuckle 

When two people go in for a handshake and one person puts up knuckles and the other person goes for a standard handshake. A fucked up handshake or a fucked up attempt at one.

The boss went to shake my hand and I gave him knuckles on accident. What a knucklefuckle.

Arkansas Knuckleball 

When engaging in intercourse with a woman from behind in the vagina, a quick, sudden and forceful penetration of the anus. Often occuring as an accident, it may also occur as a "How do you do!" to simply ring her bell.

Last time I was bangin'-it-in with that bitch, I gave her a donkey punch, so to spice things up, I gave her the ole' Arkansas knuckleball!

Knucklewagon

A car usually driven by a senior citizen. From behind all you can see is the top of their head and their knuckles on the steering wheel. This vehicle is usually driving very slow and sometimes looks like no one is behind the wheel.

Dude, I'm gonna be late for work because I can't get around this knucklewagon.

Knucklebuster

A car, usually an old American car (1930's-1970's) who seems determined to skin, slice, and slash the hands of every mechanic who touches it, regardless of their skill-level. Resistant to tools, penetrating oils, vice grips, and laws of physics. Any bolt that is in this car will STAY in this car, whether you want it there or not, and if you try to remove it, it WILL break off, and leave you requiring 15 stitches in the process.

Holy Hell.........that '49 Mercury just tore my whole hand open, and all I was trying to do was change her damn oil!! What a knucklebuster!!
