Musturbating

A term coined by American Psychologist Albert Ellis explaining that if you look at the things that anger, upset or frustrate you, 99 % of the time, you have a MUST, OUGHT or SHOULD in your thoughts.

Parents:
You really shouldn’t buy that much alcohol...

Their kid:
Well y’all really shouldn’t be doing a lot of things, but you don’t see me getting into your goddamn businesses.

Both the parents and the kid had a SHOULD/SHOULDN’T in their thoughts leaving them musturbating.
