Someone, often a girl (but not only) that dresses and/or acts like a whore.
For example, Dorian Green from Birds of a Feather is 100% a tart.

Tart can be used as an acid remark, a bit like bitch.
It's rude and mean, but often used as a funny joke between friends.
"God, that girl is such a tart.."
"Why? She seems kind."
"Just look at how she dresses. SOOO slutty!"

"God, that guy is such a tart.."
"Why? He dresses normally."
"Just look at how he act. SOOO slutty!"

"Heyy!"
"Damn, hey tart! It's been a while"
"Biiitch, ikr!"

Get the Tart mug.
A saucy, sassy young woman, who's clever, playful and dresses provocatively. A nubile young temptress.
Woah, that tart shot back the most clever comeback and sexy smile I've ever seen. She won that argument, but I'm not even mad. I WISH I knew her name!

Man, that guy is such a tart...
