Wedge rats is the term used to describe a social group particular to WPI. Wedge rats are usually associated with the Science Fiction Society (SFS) and also sometimes with the Society for Medieval Arts and Sciences (SMAS). The term "Wedge rat" refers to the tendency of Wedge rats to congregate in and around the Wedge, though in recent years since the construction of the Campus Center the community has in large part relocated to the Class of 1946 Lounge, often referred to as the Octagon or the Octo-Wedge. Most Wedge rats are self-identifying; they accept the term and are not afraid to identify with it. In some circles, however, the term is used in a derogatory manner, as the Wedge rats have a highly negative reputation in some campus factions.
