A slut that gives a blowjob and handjob. She also gets eaten out and fingered IN 1 NIGHT. She is so loose no one would ever do her. Not even a kiss, because of all of the coldsores.
That girl turned into a floosie to get another guy, because she thought he liked floosies. The joke is on her. No one likes her.
