On a person's 21st birthday, they spend the night shuffling from one bar to another, drinking one shot of alcohol at each bar, until 21 bars have been visited. The person proceeds to write the name of their shuffle on the bar walls. This originated at Ohio University, where students would start at The Cat's Den.
My bro turned 21 yesterday. We took him on the 21 shuffle.
