MTP
Magical Tea Party - a slightly derogatory term used in roleplaying system design (mostly on The Gaming Den) that refers to a freeform style of RP. Events and outcomes of the players' actions are determined by DM fiat rather than by a character's skill or chance of success.
Example:
DM: So as the DM, I decide everything that happens. There will be no dice rolling. What I say goes, and you can react however you like. What happens due to your reaction though is completely at my whim as well.
Player: So... it's basically MTP?
