I use the following term from LARP into table-top
Bleed to talk about how in game drama impacts your emotion, it's usually positive, but need clear discussion to not end-up in horror stories
Black box for flashback/workshop where you roleplay something happening before the actual game. It can be used either to clarify link between characters (especially in one shot) or be used in games like Blades in the Dark to have PC jumping to action directly and doing the preparation latter
Then the obvious IC/OOC to clarify what happens. And some game-term which I export everywher like talking about the Malkavian or the lawful good
