Pronounced in a only northern chav/scally accent.
A phrase used only by two types of people.
It can be screamed by F-16 pilots, instead of the customary "booyaa", while flying 2 meters above crowded pedestrian areas.
It is also screamed by Parson cross chavs, from the drivers window of red honda civic type-r as they speed past inferior cars(EG bugatti veyrons, saxos, corsas &/or hyundias).
The sound, honda civic r-type, v-tec engine makes at 6000rpm very similar to the sound a hyperdrive would make if you straped it to a white 1985 Vauxhall nova.
