"The exclamation mark or exclamation point is a punctuation mark usually used after an interjection or exclamation to indicate strong feelings or high volume (shouting), and often marks the end of a sentence."

You're gonna need a better argument than "kunai speed blitz oh my", or "Clone Jutsu rex him!" Because, in all seriousness, everyone sees how unreliable and retarded that sounds. Get something better and stop repeating the same shit.
