A hooray (also Hooray Benry) is in British English, an upper-class male, probably university-age or a
bit older, who thinks it's amusing to be loud, and rude to social 'inferiors',and the locals, especially waitresses. (In 'Trainspotting', the book not the film, a waitress hets her revenge by putting her tampon in a Hooray's
soup before she serves it to him.) They wear striped shirts and
try to talk a
bit deeper than normal people.
