Hamster Alliance provides examples of the following tropes:

Angrish: Devolves into this a few times during Super Meat Boy.
Awesome Music: Has shown more than once he can make this.
Badass Beard: His most recent game videos have him sitting in the corner of the screen from the shoulders up, sporting some impressive beardage. This can also be seen in previous video blogs.
Big No: Let out an epic one during a particularly punishing level of Super Meat Boy.
Cluster F-Bomb: Plenty of these to be found in his Super Meat Boy LP. For good reason.
Comedic Sociopathy: Most prevalent in the co-op of Resident Evil 5.

*Hamster playing as Chris is clumsily leaned on by an obviously infected woman* "Hey baby."
*Woman hisses and tentacle like appendages shoot from her mouth in a grotesque and painful display*
Hamsters co-op partner: wha-?
"Those are some dick suckin' lips!"

- Most of the game is largely the pair of them poking fun and snarking to one another about the generally horrific happenings of the plot; this proves to make it all the more entertaining.
Deadpan Snarker: Most definitely!
Evil Laugh: At the end of his one-shot LP of Blueberry Garden.
Laughing Mad: Pretends to do this during his Amnesia LP. It's unexpected and his quick dismissal of supposedly going crazy invokes much laughter from a viewer.
- Also happens in the SMB LP. Whether it's completely pretend or not is another matter...
Large Ham: Does this deliberately to hilarious effect.
Megane
Oh Crap: Has had a few instances of this during his various playthroughs.
Screams Like a Little Girl: Frequently does this when he gets surprised or scared.
Snark-to-Snark Combat: His co-op recording of Resident Evil 5 with a friend has frequent bouts of this.
