I think you will find that in the 20s and 30s the word truck was used instead of the f word.
A number of songs made reference to the dance called the Truck--and, seemingly, to a word with which it rhymed:
- Truckin'--Ina Rae Hutton & Her Orchestra (1936)
- Truckin' My Blues Away--Blind Boy Fuller (1936)
- Bojangles of Harlem--Fred Astaire (1936)
- A-Tisket, A-Tasket--Chick Webb & His Orchestra (with Ella Fitzgerald) (1938)
- The Walkin' Blues--Jesse Powell & His Orchestra (1951)
