FOFS is an acronym which means Full of fucking shit (formal).

Or for a lighter tone, try FOFSM, Full of fucking shit man (informal)

Circa Covid lockdowns, one of the silly moments amidst the nihilistic ones ... FOFSM
Fofs or FOFS is a word that can be used as a complete sentence. FOFS is best used in a direct, straight up way ... Misogynists are FOFS. Covid is FOFS. Putin is FOFS. Etc ...
FOFSM is the more affectionate version you use to a mate, your parents and other relatives.

1. J: I caught a fish this big ...

K: Lol! I've seen your fishing line, you are so FOFSM.
2. The previous example is FOFSM. Lol.
Probably best not to use either version at all when speaking to police, teachers, judges etc. Politicians, either version totally ok, though FOFS would be the correct usage in this context.
