substitute for any word that agree's with what a person is saying. It is also used as a substitute for anything "yes" such as for sure or yeah. This word was established in 2004 by a man named Gijo Thomas. Coincidently his nickname happens to be frosho.

A word used to agree with anything. Also an alternative word for yes, yeah, sure, why-not, indeed etc. Origins of the word are unknown but it is believed to derived from ''for sure'' which became ''fosho'' and finally turned into ''frosho''.
