Get the dumbassmug. The state of being dumb. The condition of completely blind to the fact that you should have kept your mouth shut. The reality that in the moment you are too dumb to see that what you are saying should not be said. Dumb-Ass!

You would be better off asking Lucky-UTV representatives to film your script, because you have some issues going on in yourself that are shown in your writing dialogue that are full of dumbassness.
If you want to be cured of dumbassness, simply follow the lead of the CEO of lucky-utv.
