Not sure I'd recommend them (their no. 1 target audience is teens), but here's the channels I watch the most.
The Ultimate Sidemen (British group that includes 7 people, content: GTA, random games, dorkiness, ironic homosexuality)
Kyr Sp33dy & the Crew (American group of 6 or 7 people who do GTA and bunch of games, featuring smug humor and ironic homosexuality)
A bunch of NHL channels (I doubt there's another hockey fan on here, so the most notable thing here is that these channels don't, in fact, have ironic homosexuality)
