an expression used by overly obsessed Martin Johnson fans. It prevents these kids from saying OH SHIT! or any other profanity during school hours. This is expression can be used in a good way or bad way.
Good Way:

Marki: Oh Martin, that cupcake was scrumdiddlyumptious!

Bad Way:

Marki: Oh martin! I dropped my phone!
