The act of sneaking a
naggin of vodka into a club for either:
1.
Topping up non-alcoholic drinks
2. Going into the bathrooms, doing shots in the cubicle, from the bottle (usually with a friend) for the purpose of getting drunk cheaply
1. "
Hmm this needs alcohol"
"I'll do some crouching tiger hidden naggin"
2. "The
drinks are expensive here"
"
That's okay, come to the bathroom with me for some crouching tiger hidden naggin"
