Did you just get back from Florida cause you brought the Beach with you.
(proun: san-jine-ah) a woman who plays up her sensitive, "vagina" role (slang for the classic feminine, celebrity magazine reading, hot sunglass toting, thong bearing, no adventure seeking woman) and choose to not get off her neatly groomed vag and play with the rest of the boys
The boys were really disappointed when Brittany Badass came to camp and turned out to be a total sandgina surfer.
