Hmm. Original Half-life: The suicide bomber - In the original half life multiplayer (no mod) if you held the fire button when holding a grenade too long, it instantly exploded the second you let go of it. So when I was bored, I would spam "FOR ALLAH" and run into people and let it go. Usually, I ended the game with a positive score, which shows how strong this tactic can be
The above isn't really because i'm pissed, more like, bored.
In general, I don't yell at people. But sometimes I lose my temper. I'm much more likely to lose my temper at myself.
