File System Consistency Check, or File System check is a system utility on Unix systems for checking file consistency.
Microsoft equivalents would be scandisk and chkdsk

It has been used as a profanity, as a replacement of fuck to get past autocensors/filters and also as a literal insult.

Sometimes used as general slang for to check/repair something.
