Deathnag
A withering blast of white-hot hassle from a spouses mouth which simultaneously destroys any ideas, plans, plots one might have, long term or otherwise. May also include vague or spot-on references to past indiscretions.
Upon hearing of Travis' intent to host a Guy's Night in Vegas, his girlfriend unleashed a Deathnag, thereby putting to death any and all travel plans for the next 3 months.
