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.
This phrase is popular among high-schoolers in the pacific northwest. It commonly is used as a term when you are doing something that you do not find appealing or fun. It can also be used in the future context of an activity. This phrase is very popular among high-schoolers and is estimated to originate in Oregon.
