Get the Dumbacity mug.
The tenacity or persistence to continually perform/do/say dumb things. Repeatedly performing, what most intelligent people would consider dumb acts or narrative. To always 'shoot yourself in the foot,' self-sabotage; saying something which obviously stretches the truth to fit one's narrative (usually stupid.) 'foot in the mouth' gossip or speaking ill of someone standing right behind you. Repeatedly trying to change an outcome and getting the same results is an act of dumbacity.
I can't believe the dumbacity of some people. They go out all the time badgering others in futile attempts for a different conclusion. It's over, get over it, what dumbacity! He, who shall not be named, repeatedly promulgates a negative narrative on a the LOSS he cannot understand and claims 'stolen' from him. The dumbacity of the people which believe him.
