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.
