1. HFCS is a refined sweetener made of corn. It causes a nerve ending in your brain to not detect when your stomach is full, which will lead to overeating. It also has a 1/3 chance of containing mercury.

The HFC stands for Holway Fighting Crew. This bunch of 'ard nuts go around the streets of Taunton trying to steal people's wallets or just trying to 'smack' as many people as possible. Despite these ways of intimidation all they've really done is thieve from the local corner shop and spray their HFC tag on walls around the area. So if you are visiting Taunton look out for white tracksuits and burberry hats, because they're well good innit.
'hey mate look, a greeb, let's get the HFC to bully him into giving us his wallet.
