The Suda's headword, otherwise unattested, is foualiklon (or in ms G, as reported by Adler, foualiskon), but this must be the foulliklon mentioned in Athenaeus, Deipnosophists 1.14F (1.25 Kaibel), where it is said to have been "invented by Atticus of Naples, trainer of Pompey the Great, for the purposes of physical exercise."
In Latin the form is masculine, though both Athenaeus and the Suda transliterate it as neuter.
