F-back
n.— «The “F” stands for “full,” as in fullback, but like most words in football parlance, the term makes little sense. The F-back incorporates several different positions including fullback, tight end, running back and wide receiver.» —“F-Back To Rescue” by Kevin Lynch San Francisco Chronicle (California) Aug. 1, 2006.
