Someone who is bi-sexual. They aren't sure if they are gay or a lesbian a not so instead of feeling like a rainbow they feel like a rainbow?

slang word used to indicate a police officer in the area of where the officer can overhear you. rainbow is being used because when cops turn their lights off its a bunch of colors. and its better off the officer dosnt hear you talking about him like oh my god its the fucking police!
