The term originated on Dec. 30 2004, when someone, under the guise of "having to leave to hang out with
Don Masterson," really just went home to drop a deuce so large, God himself couldn't create a larger dump.
Usage includes but is not limited to: "Hanging out with
Don," "Big
Don is coming over," "Big
Don has launched a full scale attack," or even "D(on)-Day."
Usage does NOT include referring to the actual deuce in question as
Don Masterson, but actually the action is what is being referred to.
"Hold on, Big
Don is coming over."
"Sorry I was late, I was hanging out with
Don Masterson."
-Were you
masturbating in there?
-No, Mt. Saint Masterson erupted.
