Tiro means ruler or master. A determined man who is a ruler and owns everyone and everything. In games you may call others a "Tiro" & they might be confused about it. But you know yourself that it means a ruler or master. They may also be a Tiro from how they act. If they act like they're the SHIT. Call them a "Tiro"
Stop being such a fucking TIRO!
You play the game like Tiro.
You owned me TIRO!

Added to the end of written insults (most likely graffiti) to say that even if it is removed, then the fact remains that the insult is true. Usually based around truth.
