TSR's Super Smash Bros Thread|SWITCH HYPE TRAIN NOW BOARDING

[NICKtendo DS]

Is it possible to tell someone's a giant prick based on how he or she plays? Because when I played online yesterday, I had the greatest time fighting what could easily be my Smash rival in 1 v 1 For Glory, having lost more often than I won. I didn't care, I had fun. It felt as if I was honing my skills sparring with him.
But today I faced someone of equal, maybe tad greater ability, but he frustrated the shit out of me. It felt as if I was playing against a dick, but it's impossible to tell aside from his playstyle and changing his name to "Hahaha". "Hahaha" might seem like a give-away, but it's still hard to tell the intended tone. Either way, instead of calmly accepting my defeat and psyching myself up for the next match, I just raged. What the fuck is going on? Is it me? I'm starting to feel the DLC is eating away my patience, but that would be such a childish excuse.
I already told my mother I only rage at CPU players, not at human players. Now I have to tell her I lied. Shame is had.
