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!

When a female engages in pleasuring herself and whilst doing so creates a puddle so massive that it could be confused for a the disintegrated remains of a human.
I moisterbated last night so bad that I had to get a new mattress let alone change the sheets!
