In Monty Python terms, English upper class twits - public schoolboys who turn into oiks and behave rudely, noisily and foolishly in a group at public functions rather as European players of rugby football are commonly said to comport themselves at social events. The females of the species (rarer)are Hooray Henriettas.
A cultural phenomenon, to be a part of which includes becoming sufficiently hounded and clubbing for those cognitive enough. The night ends deep into the AM at the persons house closest to the city, and the morning after involves watching tv and feasting on mcdonalds breakfast.
The term used for someone that shows promise as a long term relationship. The antithesis to "shiny pussy." Goes beyond sexual satisfaction and is usually a surprise to one that experieces it.
1. "I thought it was gonna be a one time thing but she put that 'hooray pussy' on me."
2. "I said 'Yes' beacause he said 'Hooray!' after I let him cum inside me without a condom."
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.
