Non-mechanical use of fictional events or resources to apply pressure in role playing games to affect actions decisions by other players and actions by characters (or other outcomes in the game). 

Leverage in gaming, by Emily Care Boss (Fair Game, 18 April 2007.)

Lumpley Principle (or Baker-Care Principle or Baker-Boss)

The fictional events of play in a role playing game are dependent on the concensus of the players involved in order to be accepted as having occurred. All formal and informal rules, procedures, discussion, interactions and activities which form this concensus comprise the full system used in play. 

"System (including but not limited to 'the rules') is defined as the means by which the group agrees to imagined events during play." The author of the principle is Vincent Baker, see 'Vincent's standard rant: power, credibility, and assent and Player power abuse' [thread in the Forge Forums Archive]."

Phys'ing Break

Pause in play for energetic, often uplifting, interlude such as dancing or physical play. Physical activity intended to re-charge and connect players. 

Inspired by dance break on Weekly Affirmations show (HyperRPG Twitch Channel) during 1 July 2016 show with Whitney Strix Beltrán, Sally Jordan and Aya. 

Informed by SlayerCake larp by Katherine "Kat" Jones and Evan Torner, in-game band air-performances & audience support & cheers. 

Term from Questlandia campaign playtest world building, Spring 2016 with Evan Rowland, Hannah Shaffer, Rebecca Slitt.

Analagous to warmup exercises, as in Nordic Freeform tradition, but used during course of play.

Background from Concensus Decision Making structure of discussion, exercise commonly used in this and other discplines (mediation, improv acting, etc.).
