guarm

"It is dirived from a story involving a man named Graham one day Graham was walking happily along .. for once he was doing nothing "naughty" but because he was in Wynumm there were pulled up to by to police officers... One of the officers then realised he knew graham ... said "Ohh your that GUARM fella"

Thus the Guarm word was invented .. by some hill billy silly copper from out wynumm way that couldnt pronounce Graham .. and from that point on Guarm was used when somthing was unsavoury, nasty or stupid

It has nothing to do with the island

Guarm is a word used for when you're destroying someone in a video game.
