I do (well a lot). I rage (to the max of my rageness [wtf does that mean]) because I get mad easily (well a little too easy for me to rage).

I can't remember doing it but its a likely event ¬¬

Somewhat..usually I only rage when a gym leader/four heavenly kings/champion uses a full restore when I come close to defeating them in a battle especially when my Pokemon is at a low HP level..or even when an attack misses in a big situation or when the opponent gets lucky with a critical hit in a big situation..or when I come close to capturing a Pokemon and I run out of Monster Balls/Pokeballs.

Pfft. ¬¬
I broke a DS Lite because of a Pokemon game.

I get so angry at times that i don't even burst it -_- No need to say how many pissful moments there can be but yeah later i do burst out "WAHHH"

I broke my ds =.=

I rage when a gym leader uses a full restore when I am so close to beating them or if the pokemon they use has a high base stat and then boost its stats to the max, making it harder to defeat them. Or if a pokemon is too stubborn to stay in its pokeball. Another one is when a pokemon trolls me by using a move that is super effective against me when the pokemon doesn't resemble the move it used (Ex. Umbreon using Physic against my Infernape).

Nearly impossible not to rage at least one time in a Pkmn game. -.-
And very possible to do it several times.
