A girl who flirts with many, many guys at once, leading them on and ultimately screwing them each over. Flirt Sluts are generally immature with relationships, and/or have self-esteem issues.
If you know a girl like this, stay the fuck away from her. Trust me, they aren't worth the trouble, and shes not good for your sanity.
