As long as I'm quibbling, the term "obfu" isn't actually an acronym, rather an abbreviation.   Like the GBians who say "telly" contrasted with USAites' "TV".

Now if we look at the term "fsck", it appears to be a combination acronym+abreviation of "File System ChecK".   So does that make it an acroviation?   Or a CAA?   Hmmm... howzabowt abrevonym?   ;^D
