約炮 [yuē pào] v. Appointment+cannon. To have casual sex such as one-night stands and other related activity. This Internet slang term is created from a male points of view because it is a combination of 約會 [yuē huì] “to have a date” and 打炮 [dǎ pào] “1) To open fire with artillery, 2) a slang term for having sex (with a prostitute), or 3) to jerk off.”
