n. the physical and psychological discomfort that arrises from the crushing realization that the body art that seemed so perfect at two in the morning after an unknown number of cocktails is hugely embarrassing in the sober light of day.
"Last night Ricky J. was showing off his multi-colored 'Ricky Is A Momma's Boy' tat to everyone he met, but this morning he has a tattoo hangover at the thought of having to live with it the rest of his life."
