That whole no homo thing is super gay.
I know a lot of people don't wanna hear this but I'd say there's a very very high chance that Cam (and maybe other dips) are batty riders. Check the repeated references to anal rape (male or female), blow job songs, making it cool for NY thugs to wear pink and the icing on the cake, constant denials of homosexuality. I actually rate him for all this, think it's a testament to his skill that he could singlehandedly make it OK to act very gay and have that go largely unchallenged.
Regardless, anytime people start repeatedly and aggressively denying their homosexuality something funny style is going on. Regardless of what I say I never feel the need to deny that I'm gay, and if it ever comes up it's usually pretty funny.
As far as all the British kids copying NY, I think it's mostly boring. I would much rather listen to JME talking about 'I need some kebab rude boy' then anyone in the movement yelling about shanks and selling coke. I feel like the crack rap gangsta era in hiphop is running out of steam and they're all arriving late with not much to add to the formula.
