One who cuts themselves to releive themselves from an emotional pain.
Cutting is not something one advertises, and when someone does cut they are generally ashamed and hide it as well as they can.
Can be done with any sharp object, such as, but not limited to, knives, razors, broken glass, broken cd's, scissors, and safety pins.
SomeGirl: OMG, I adore Emily, she is *sooo* sweet!!!
AnotherGirl: Yea...I spied on her in the shower and she had slashes all over her thighs... she so cuts herself...
