Stockton regularly does something I really wouldnt consider yakin out the neck, because that usually implies some sort of exaggeratin, outright lying, etc., to make oneself seem more informed/entertaining/in the know, etc.
In his case I would label it "talking out the tonsils", maybe "talking out the appendix", simply for the fact that it is ridiculous, strange, and comical in a new, uncategorized sort of way I have yet to put a finger on.
