Dualfront

undefined:

The state of having two fronters all or most of the time. A dualfront system always or almost always has two alters fronting simultaneously. These may be the same alters or they may vary. They may develop pairs that usually front together, but they need not do so.

This term was coined by the Ironwood Collective on Tumblr. It is not exclusive to systems of any particular type or origin, only to systems in general.
