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!"
