Crusty Knuckle

After someone has fisted another person, they leave their hand uncleaned for a while. The fluids, dry and harden on the hand, forming a Crusty Knuckle, or Crusty Knuckles depending on the severity.

Jasmin fisted Leeroy. She left her hand overnight an the shit hardened. In the morning her hand had turned into a Crusty Knuckle.

Knuckle Blasting

Getting a tattoo of letters on each finger (generally excluding the thumbs) in order to spell a word or words about eight characters in length. The tattoo goes between two knuckles per finger on the outside of the hand.

"I had a little knuckle blasting session last weekend at the tattoo shop. It says 'hold fast' because I'm a sailor."
