When something is turned to rubble as in Barney Rubble.
Guy one: I just totally got in a car accident
Guy two: Homeboy! Your car is totally barney'd!
when a person overdoses on watching children's videos and listening to children's songs to the point of forgetting who they are, wanting to tear their hair out and run through the streets screaming to find some relief from the self induced kiddie-coma they experience on an almost constant basis... originating from the extremely popular children's tv show "Barney" about a purple dinosaur.
Its your turn to be with the baby... I'm all barney'd-out and about to go postal with a semi-automatic.
