I occasionaly snap pens in two or slam them into the desk, shout the c word (medium shout), or open palm slap/punch of my soft furnishings. All pretty tame.
That's when I lived by myself, when I'm around other people I can control myself easily enough. The occasional loud sigh or groan is all anyone is going to witness me doing.
A bit of rage is ok imo, like if you're watching a football game and your team gets scored on. Smashing up hardware is probably a step too far. You might want to look at that.
Are you Kenneth Williams?
