Communism. Straight up communism.
For context, in Mario Party 1-5, DS, 9, and 10, landing on a Bowser
Space would yield one of several...less than admirable outcomes (stealing coins, stealing stars, forcing a rigged minigame, etc.), one of which is called Bowser Revolution.
When a Bowser Revolution event is pulled, the game takes every last
coin from all players and divides them up equally between everyone, regardless if they had less or more coins prior to the event (hence the nickname).
Great for those
lagging behind, infuriating for those with the
coin lead.
