According to Brian Jones, in addition to skill on the mat, jiu-jitsu involves: terminology (Mission Control, Zombie to New York, Clear the Neck to Chill Dog; seems like we've got terminology covered), lineage (Carlos Gracie/Jean Jacques Machado, Eddie Bravo...lineage, check), that promotional thing (???), and philosophy (choking people out is a good thing/ getting choked out is a bad thing; check).
I guess the only question is, what is "that promotional thing?" Is it a buy two private lessons, get a third free promotion? Is it a for a limited time only, sign a one-year contract and receive a free T-shirt promotion? Is it posting dogmatic videos about antiquated modes of training in hopes that people who already agree with you view you as a soldier in the conservative movement?
Or is "that promotional thing" a reference to the practice of receiving a belt promotion from someone who holds a high enough belt to award that promotion. In that case, see lineage. Checkmate.
