I am going to stop by the Bean Fiend tonight, hang out on the back deck, for a quick Hipster Speedball before I ride my fixie downtown to check out Hadag Nachach. You've probably never heard of them.
Traveler 1: Why are you taking a Starbucks double espresso with you on the plane? I thought you said you were going to try and sleep off your jet lag?
