kutsu can mean pain or anguish, and was given to me by my friends because: a) I'm in a martial art which bases it techniques on pain b) I like to cause pain c) I have a constant head ache. I'm off to find some asprin.

Update: Since someone meantioned it, I go by kutsu and not kutsuu because many older video games only allowed 5 characters and kutsu is technically correct.
