Undercover Lover

Non-alcoholic drink disguised as a cocktail; commonly drank by pregnant women not yet ready to make the news public. Ex: soda water with a lime in a tall glass that appears to be a vodka tonic.

I discreetly ordered an undercover lover from the bartender so my girlfriends wouldn't know I'm not drinking.

Undercover Nigger Lover

A white person who has sex with black people, but finds it shameful to tell their white friends for fear of rejection or ridicule.

Tim's dad kicked him out of the house & disowned him when he found out Tim was banging black girls. He tried to hide it by being an undercover nigger lover, but all UNL's eventually get caught.
