The act of masturbating and not getting hard, so you masturbate more
and more until
don't get hard but rather you are left with a very painful
raw spot on your penis.
For a girl, a masturfail is when they finger
themselves so much that eventually they made
the inside of their pussy
raw and in some cases, until
it bleeds. For both boy and girl, it is very painful
Hot Chick: Hey, you wanna fuck tonight?
Guy: I would love to, but, I masturfailed
Hot Chick: Oh that happened to me a few weeks ago but it's all good
now. Another time then.
Guy: Yes, another time.
Guy1: Ahhh, I had this huge masturfail last night. It sucks.
Guy2: Dude! Don't tell me stuff like that!
