God, I hate that "YOU'RE TOO SLOOOOOOOOW" taunt.
It's one of the best taunts in Brawl, as its tauntiness reigns almost supreme, up there as one of the tauntiest taunts in Brawl, and one of the few that can really tick you off, especially if spammed.
The only people whose taunts come close are Pikachu, Dedede, and... uh...
...Nope. Not even Pikachu or Dedede comes close to the "YOU'RE TOO SLOOOOOOOOOOW" taunt spam. It's by far the most effective strategy in the game.
Hell, I almost lost a game in which my opponents were both Sonic and just spammed taunt over and over and over and over and over and over and over and over and over and over and over and as soon as I got distracted, they began combo'ing the hell out of me, then stopping prematurely to go back to taunting...
