FOSA is an acronym for "fuck off straight away" and it is used to express a feeling of dismay or frustration.

It is similar to the popular internet acronym GTFO. However, FOSA demands an immediacy which GTFO does not have, thus making it a superior term to use when wishing someone would fuck off... straight away.
