Provocative [proh-vahk-uh-tiv] is either an adjective meaning, "provoking, stimulating, encouraging" or a noun meaning, "a person, place or thing having a provocative nature."
Here's a sentence:
What does your character do to provoke interest or action?
PS--One of the neatest people-watching things I ever did was when a group of friends (male and female) went to a Hooters restaurant. I munched on wings, listened to the conversation adding the occasional "Yep," "Uh-huh," and "You're kidding," but the whole time I was watching the provocative interplay of the waitresses and male patrons. They flipped their hair, they winked, they touched, their lips pouted and pursed... All those things you know from Psychology 101 that are meant to attract a mate, all beautifully portrayed like I was a game photographer for Wild Kingdom watching an exotic bird's mating ritual. How much fun!
