- Fosh was formed from a blending of fo sho, which is a clipped form of for sure, meaning definitely. The term is used in the same manner that fo sho is used. It is usually used as a positive response to a question. The speaker coined the term because it is faster to say fosh rather than fo sho because it turns the word from two syllables into one syllable. This word is currently found among high school students in St. Louis, Missouri and may or may not be spreading to other high school students around the country.
fosh
blending; noun
fo sho, for sure or definitely. An affirmative reply
Etymology : Fo sho- clipping from for sure. For sure was formed through metaphor because there is a connection between something being for sure or definite and the answer to a question being yes.
