There are 2 scopes of thought on this:
1. Devvo is NOT real, he is simply a friend who is taking the piss out of chavs
- How come devoo never attempts to steal the camera?
-He kicks the ground and makes a fool of himself in "Devvo As Out"
-The way he says "Aite une wat une up tune?" in a comical fashion.
2. Devvo IS real
I mean come on i have seen thousands of devvos everywhere, this is possibly his normal behaviour.
- He does take drugs in the film, no actor would take it that far
- He says some incredible things that cannot be made up.
- He really does mug that guy..
"ya what Dicked"
"fucking GAYBUS, u gay"
"I got this car for my son, dont turn though"
"look at fucking space head over her, proper bolluxed"
