1. (noun) Similar to a Pocket Slut, a selective slut, acts slutty, sexually uninhibited, and loose, but only to entice the guys she's attracted to. She'll wear tight clothes, talk and act skanky, and dance like a ho, trying to get attention, but gets offended when guys she's not interested in (ugly guys) hit on her as well. A selective slut apparently doesn't understand that her actions effect all guys, not just the ones she's interested in. When a hot guy takes notice of her, he's being "responsive to her sex appeal". When an ugly guy takes notice of her, he's a "leering pervert".
2.(verb) A girl "selective sluts" a man when she acts overtly sexual towards him, but turns off her charms as soon as someone else is watching... usually.
