fosh
n.— «Roger Clemens just started doing the “Fosh” and he’s already got another pitch to make batters” knees bend. Tom Gordon thinks the fosh may be his newest out pitch. Like a dance craze that sweeps the nation, the “Foshball” is all the rage in the Red Sox clubhouse. […] It’s held like a fastball, except the fingers are spread slightly apart. It works like an off-speed split-fingered fastball, or a changeup that breaks. Fosh, by the way, is an acronym for the unprintable feeling you get when you watch one go by. The “F” stands for “full,” the “O” is for “of”; the rest Nipper would rather not say.» —“Sox pitchers hit with ‘fosh fever’” by Jimmy Golen in Fort Myers, Florida SouthCoast Today (Florida) Mar. 10, 1996.
