Any girl who flirts amongst numerous guys just to show off and or think shes "THE SHIT".
A slut will most likely wear her cloths tight or shirts up a little so her stomach or such shows. Mostly, also trys to show her boobs, OR for that matter, make it look like she even has boobs.
Kayla: Hehehehe ( ;D )
John: Dude, shes such a slut.
Cameron: You can say that again.
