:fscking: /fus'-king/ or /eff'-seek-ing/ adj. [Usenet; common]
Fucking, in the expletive sense (it refers to the Unix filesystem-repair command fsck(1), of which it can be said that if you have to use it at all you are having a bad day). Originated on {scary devil monastery} and the bofh.net newsgroups, but became much
more widespread following the passage of {CDA}. Also occasionally
seen in the variant "What the fsck?"
