broke 3 mice
old tube monitor stopped working because i used to hit it a lot, but now i got a flatscreen so i cant afford to punch that one.
broke my old cellphone, badly damaged two other ones
once i dug my fingers into my keyboard and ripped out a lot of keys though i could put them back together, also i used to hit it a lot and actually slapped out the "console" key
broke a calculator (actually tore it to pieces) like 5 months ago, i still find buttons lying around every once in a while
split a drumstick by throwing it at my rock band guitar
broke many meaningless stuff like pens, plastic stuff and 2 days ago y threw my wallet across my room too hard and it landed on my lamp's screen. now it has this big opening but its still good i guess
games make me mad
