When someone is incredibly talented at Mario Party. Not just lucky, but has pure, god-like talent.
Also, one who does not pick a woman character. They always lose. Pick a man.
They always win.
Gstache beat me 46 times on Mario Party, he is a Mario Smarty. Fo sho.
I can't believe JBN picked Daisy, he got creamed 46 times; I didn't even have to use my Mario Smarty powers
