Get the kysmug. A KY yard sale is the burning of your other half’s items after a traumatic breakup, ie….cheating and the like. Similar to throwing out the window to destroy items.
Damn, did you see the KY yard sale after Denise caught Dwight cheating on her.
Bro, it was the talk of the neighborhood for weeks.
Yep, see you Dwight and damn.
