When you pay for your friend's drink before they even ask you, just so they can embarrass you later. It's like a cursed list on the bar wall that everyone knows about.
I bought my buddy a drink before he even showed up. Now he's gonna make me buy him another one when he gets here.
The bar has a whole B. A. B. A. D. list. It's got my name on it three times.
I paid for ten drinks for my cousin. Now he's gonna show up and order ten shots of tequila.
