I agree that the name should bring up an image that is game related and a big troll powerskating down the alley is quite evocative.
You might even want to have an image designed to match to serve as your logo for the site. So take one of the bigger WWE Divas, since you are pushing for the idea it is only fair the mascot is a lady - plus a good artist can still make a pretty hot troll- fan service sells afterall

, add some horns and tusks along with some motorized rollerblades and a mono-edge hockey stick or other street weapon of choice and you are good to go.

Plus if he is worried that the title doesn't match because there is no troll currently in the group, consider some of the other podcasts names.
Critical Glitch is not dedicated to massive fails, but rather again it is a situation that occurs in game, so it is a name players can recognize as being game related and just catches the eye.
End of the day, it is you and your table sharing your gaming sessions, comments, thoughts, winning highs and crushing losses, etc...and that will be more the test than the title itself.
