The act of performing extremely violent self sexual pleasure the morning after a night of heavy drinking and not getting laid. Usually leaves self inflicted puss oozing wounds and burns that can last up to 2 days; eventually, they turn into scabs then heal.
The guy who didn't get laid the night before decided to take his anger out through angry masturbation on a hangover.

or:

(during the act) "Damn you YAM RAAAHHH!!! You sat on my BALLS ARRRGGH!!! I HATE YO! RAAAH!!!!"
