The act of masturbating furiously with extremely sweaty or clammy hands, creating friction burns on the shaft and making it impossible to finish.
Dude I was moisterbating so tough last night and now my cock burns like a mother fucker. I won't be able to jerk off for at least a week.

I hate it when my dick bleeds after I moisterbate hard with my sweaty hands. It just completely ruins my day!
