Randomly started cursing/swearing
Talking smack like the computer cares
Scream out/ Shriek battle cry in triumph
Copy the mannerisms of your character (stab, shoot,....grunt)
Pretend to be exhausted yourself after a hard fought battle (Kill a Colossus anyone?)
Sweat in anxiety when puzzles/bosses can't be figured out
Lean back/forth with the controller
Duck when going under something tight (Driving/Flight games, you sick perv!)
Make a remix in your mind to a game's soundtrack
Most of those take place in Brawl Boss Battles on Intense level... and I still haven't beaten it
