buy you a drink?
(Can I) buy you a drink?
1. Would you like me to purchase you an alcoholic beverage? When used literally in this way, this offer is usually extended (at an establishment that serves alcohol) to a friend or someone with whom one is pursuing a relationship of some kind, often a romantic one. Hi, I couldn't help but noticing you from across the room. Can I buy you a drink? Hey, pal, I'd love to catch up. Buy you a drink?
2. Can I make you a drink? In this usage, the phrase is used humorously, since the setting is not a place where alcohol is for sale. A: "Buy you a drink?" B: "Ah, I'll just have whatever kind of beer you've got in your fridge."
