We call those people Non Educated Delinquents NEDS up here. to spot them here are some tracking tips.
1 They gather in small heards under street lights on in parks.
2 All wear the same style of clothing thats too big and there trousers falling down
3 Basball caps are worn backwards or to the side.
4 walk like there testicles are swollen with there arm swaying.
5 Unable to form a sentance without the words Man,But,Youknowwhatimean ( its sounds like one word when spoken)
6 Drinking habits are whatever alcohol they can get from local shop and its not quality its quantity.
7 diet includes Chicken twizlers,Anything fried, No fresh food only plastic wrapped and they well run at the sight of fruit and veg.
Hope this helps with ID the culprits.
