Brawling online with idiots that spam Kirby's Stone or Sonic's Homing attack doesn't bother me that much. What bothers me immensely is when they WIN with these tactics.
If I notice that I've been beaten by a dude who is clearly worse than me by virtue of Golden Hammer - Final Smash - Fan combo or overreliance on Special moves as stated above, I secretly wish everyone in the house could go for a long car drive without me so I could become the Angry German Kid.
If you dare, for one second, side with the aforementioned Kirby and Sonic n00bs, you do not deserve the Internets.
Side Note: There was this one time in which I deleted my Mario Vs DK: Mini-Land Mayhem save in preparation for returning it for store credit, but when I found out they couldn't accept it because I'd peeled off an OFLC sticker they probably had loads of I was prepared to punch somebody in the face, but the only two people within punching range were girls...
so yeah.
