"Nuck tats" are messages tattooed on someone's knuckles. If it fits, anything goes.
Each round in NUCK TATS, one player reveals a customer — a celebrity, character, mythical creature, whoever — and everyone else writes nuck tats for that customer. The best tat wins the round...and if your friends make you laugh, feel free to throw them a tip. It's that easy!
