I may experience a surge of anger now and then if my cable becomes real slow.
I also get angry if I accidentally hurt myself, like if I bump my head on a surface, or bump my leg on against a table, or if something cuts me. I retaliate by kicking the object, throwing it, or attempting to break it. Only if it causes real pain. If it's something little, all that's necessary is an under-the-breath curse.
Hard/impossible/unfair video game A.I. or puzzles can also get me raging. I only start swearing though, nothing physical with my merchandise. Although I may unleash my fist on the floor.
