You spot this weird guy smiling and happily singing "Lalalala I'm the strongest guy! Lalalala!" And as soon as he notices you, he approaches.

Yo! name's Jin Mori, and i am the better fighter in this world! Basically, i've never lost a fight (299 fights, 297 wins, 0 losses and 2 draws.) I bet you want to fight me! I won't use taekwondo if you don't prove you're a strong guy, hehe.
