What is the definition of Artsiest?

An 'artsiest' is like a sleepy, slightly bewildered artist, someone who's so preoccupied with their creative process that they're half-asleep with their paintbrush. Think of it as a painter who's so lost in their own little dream world, they're painting a masterpiece but only half-done, with half-pressed brushes and a half-drawn subject.
