failslut 

A person who would be defined as a slut, except their promiscuous attempts are in vain.

Person 1: Dude, that girl's saggy tits are almost hanging out for everyone to see. She leaves nothing up to the imagination!

Person 2: ...which is ironic, because she isn't getting any. What a failslut lololol
