Backronym

A bacronym or backronym is a phrase specially constructed so that an acronym fits an existing word. For example, NASA's "Combined Operational Load-Bearing External Resistance Treadmill (COLBERT)" was given that name in recognition of comedian Stephen Colbert's attempts to have a space module named for him. Backronyms may be invented with serious or humorous intent, or may be a type of false or folk etymology.
