A Mong is 6 foot odd of genuine idiot. He will ride a motorbike and drink beer. Usually named Dave, he is quick to temper yet normally wont do anything about it as he does not want to stand up because he has soiled himself. He will make outragous statments like "I invented the full stop" and accuse rocks of slagging him behind his back. Legend has it that Mong once smoked so much dope that he tripped out and thought he was a carpet salesman from ashbourne. He has little time for women and will not engage them in conversation unless they are offering sexual services for a decent price. He has a few friend's of his own choosing, usually made up of parinod, rapist hillfolk and slow dim-witted friends of his geeky brother.

Mong is short for 'mongoloid', which was originally an anachronistic term for a Down's Syndrome sufferer. The modern Mong however is a total fuckwit, who deserves nothing less than complete humiliation for their idiocy. That includes all those dope smokers too, who relate being 'monged' to being chilled and mellow. Its because when you're stoned you act like a fucking retard, you fucking spazzes!
