A hook up with the sole purpose of
raising one's
self-esteem.
A person (usually a girl) trying to fuck someone so that they can
reassure themselves that that look good/are still skinny enough for others to desire them.
"Did you
hook up with John last night?"
"Yeah, but it was just
a skinny fuck. It didn't mean anything and now
I feel better knowing at least John still wants to fuck me."
