Cool person. Though in Star Trek the character is not important, in real life she is very lovely hot
(even her name is) and smart. You'll instantly want to become friends with her because of her free flowing personality and her way with words. Though she's not the best singer, her dancing and instrument talents are great. She often has dark brown hair and is tall.
Guy 1: So did you meet that girl, she was smart, pretty and nice!
Guy 2: Yeah! I did meet her, she's such a Troi.
Guy 1: Woah! And I think her name is Troi!
