MRP stands for Mature Role-Play. Role-Play in this definition refers to the typing RP done in video games, chatrooms and forums.

MRP is role-playing that may involve violence, strong language, drama and quite often sex scenes, though unlike ERP, the scenes are a sub-product of the RP, not the whole RP.

MRP will usually be a long term role-play and anything that happens in the RP will effect the characters for the rest of the storyline. MRP is suggested only to those who can understand adult situations and consequences as well as those who do not mind having their character die or change completely if the RP calls for it.

MRP is basically RP that is rated R.

The term is often confused with ERP by people who think maturity means sex, but it is very different.
We should have an MRP to develop the characters.

The group encompasses all from the hot QB to the riverman. Known for excluding girls from parties, these boys know how to throw a mean get together (although occasionally too anti-social for their own good).
The MRP is horny but still not getting any.
