When you are too high to show up to school or work because you took dabs (highly concentrated THC wax heated and used with a glass nail or a skillet)
Ben: Wow, that was a fat dab, I think I'm too posted to go to school now.

Evan : Yeah, I think I'm going to be dabsent too.

Ben : Unexcused dabsence, fooook yeah.

Evan : I'm hungry.
