A woman that fucks around behind her friends or lover's backs with numerous men, with no feeling what so ever for the people she is hurting. A trashy, deceiving, back stabbing, lying heart breaking, cunt. Doesn't care what she does or who she does it to, as long as people are talking about her, weather it be good or bad, she's happy. Wherever she goes, drama is sure to follow.
"You slept with my boyfriend, my best friend, and my brother !"
"haha, yeahh, I hope my boyfriend doesn't find out."
"You fucking slag."
“Chloes a slag,it’s been 5 weeks since you broke up and she’s already fucked someone”
