Scallies use words like 'nyeh' i think its a combination of both no and yeah, when they disagree with you they like to say 'nah mate' and they often like to call 'ya mam' as you walk by.
Male scallies are easily recognised by their tracksuit, pants tucked into socks? (don't ask me why) blue/white hoody or baseball cap all nike, reebox or addidas for real scallies and usually seen with a bike and gold sovereign rings hang around in groups of 5-7
Female scallies wear tight clothes and large earings, and don't forget the clown necklace.
