A fake word used by idiots (millennials mainly), in an attempt to turn the adjective adult into a verb in a feeble attempt to describe if a person is actually an adult or behaves in an adult manner and thus doing the things any responsible adult with an average or above IQ can handle. You cannot "adult" something. It is as bad or worse as the overuse of learnings in the corporate world.
Jane is so responsible, she pays her bills on time, walks the dog, grows her own food and calls her mom every week, she is so good at adulting.
