Knuckle buster 

While in spoon position with your partner, you put your pinky in the Booty hole, ring and middle fingers in the vagina, and use your pointer finger to stimulate the clitoris.

Whether my wife is being naughty or nice, I always end the night with a knuckle buster.

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!!
