Undercover Ginger

One who does not show visible signs of being a ginger (ie red hair or freckles), but days of not shaving reveal red facial hair. This allows the individual the ability to hide ones gingerness from the world.

By simply shaving his red beard, Tom was able to hide his true ginger identity and go about his day as an undercover ginger.

undercolletted

when you haven’t heard from Collette in a while, haven’t had enough contact with her in the last 24 hrs or when she hasn’t send pictures of her as promised, you feel undercolletted

A: Collette’s been busy the last days, huh?
S: YESSS, I really begin to feel undercolletted. It’s hard!

Undercover Slut

A girl who one would not assume gets with a lot of guys (whether because she is weird, nerdy, or just really nice) but in reality has hooked-up with half the school.

Bob: That Mindy girl's pretty cute, she seems really smart though. I wonder if she'd get with you.

Joe: Dude, she's an undercover slut. She gets with everyone!
