An attractive person of the opposite sex that looks sexually appealing from the rear (9) and not so sexy from the front (4).
Person A: Dang, did you see that girl walking into the restaurant?
Person B: Yeah, she looks super hot. Let's wait for her to turn around!
Person A: Look! She turned around. Oh man... she looks good from the back but not from the front.
Person B: Yeah, she's definitely a 49er!
