Idiot expression used by those with low intellectual capacity. An alternative to asking "What are you doing". Not to be confused with WHATTAYADOIN or WHAT THE HELL ARE YOU DOING?!?!
used not as a question but more as a statement as if to say "stop that now because you lok like someone who doesn't understand socially acceptable behaviour"
usually complimented with a sigh, a look to the floor/heavens and a shaking of the head
