crysterbate 

To masturbate whilst sobbing in a torrid combination of lust and anguish. Presumably a growing trend among the emo crowd.

The night Becky broke up with me I got home and just crysterbated to old pictures of her for hours until I finally passed out in my computer chair, still gripping my dick in my tear/semen stained hands.

James: "hey Pat, did you hear Alex broke his wrist?"
Pat: "yea, too bad he isn't ambidextrous, I bet his cock is burning from having to casterbate all week"
James: "I heard he deliberately broke his wrist because he enjoys the chafing"
Pat: "man, what a sick fuck"
