I don't think Osiris are trying to insult you with the name of this tee. I assume it's just the name of the skeleman on the back, legging it around looking angry with a tattered Osiris flag. Whatever floats his boat. The Osiris name is printed on the front in a proper skatey-looking font plus on the sleeve, and there's a branded pinch tab on the front through pocket.
