For all the people that when they pick Captain Falcon, they quickly press the taunt button to have Captain Falcon taunt his opponent by challenging him to "Show me your moves!"
Sometimes, you even pull of the taunt multiple times at the matches beginning.
This tactic also usually works as an insane mindgame and sends your opponent spiraling towards their doom.
Or, if you just love Captain Falcon and his sheer manliness, or if you taunt ever possible chance you get in the entire match. Then join.
