The act of masterbating because you hate yourself. The desire to masterbate due to self loathing. The self love equivalent of "hate fucking".
I was so ashamed that I lost my job that I went home and masterhated.

when you masturbate all your pain away to angry disgusting porn that you would watch never normally, just to vent your crappy situation through your penis.
