fry = F = FSF

fscking /fus'-king/ or /eff'-seek-ing/ adj.

[Usenet; common] Fucking, in the expletive sense (it refers to the Unix filesystem-repair command fsck(8), 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?"
