A word in the Talish dictionary. It is a combination of exausted and exacerbated. Occurs at the peak of annoyance when you would just rather be sleeping than dealing with that annoyance.
This word is a verb
I was so exaustriated after my parents found out about me sneaking out last night (and consequently not getting any sleep).
So exhausted and tired that one flops down upon the couch and is too pooped to say both "exhausted" and "tired" as separate words and therefore combines them.
Rose face planted in the center of the lunchroom and mumbled "I'm so exaustired."
