>What emotions are subhumans allowed/able to exhibit when they're doing one of their favorite pastimes?
What do you mean?
We are talking about holding back a smile, which is another way of saying "pretending to be serious." The dude in the webm is pretending to primal retard, which he finds funny so he's holding back a smile. It's not that he's not enjoying it or that he's not allowed to smile.
Ever played retarded among your friends? And when your friends start to laugh and you try to keep a straight face while continue playing the retard? That's the expression the tree ripping dude has.
