Charvae are distinct even when naked, because of their gaunt appearance and the look of borrowed flesh, hanging loose from their bones due to their peculiar dietary habits which leads them to malnourishment. The charva food-cupboard
comprises tinned hot-dogs, baked beans, pasta'n'sauce (for the posher ones)and may even stretch to a packet of dairylea, all bought in mountainous bulk on giro day from Netto (or maybe Morrisons if they're walking home.) White cider is the chosen beverage, which is taken several times a day at intervals, with class B drugs. Celebratory splash-out meals are had from time to time, when charvae 'get raj' at McDonalds.
Despite being pathetic, doomed losers and non-achievers, creatures that we all wish to help, charvae do have value, as they are walking, breathing examples of the importance of birth control.
