It isa game, either a frookies or a rookies, which someone holds and asks their friends and others to fill the game up with the intention of letting the charity holder win. It is normally done for either 100 game milestones (100, 200, 300, etc.) or in order to be able to buy the next color level, so a sky charity if they need to win a frookies or rookies to become sky. I dont recommend holding one for a color levl if the color level is below black though, people dont take well to that. but yeah in a nutshell its a game where everyone mutually agrees to let one person win
