ICSWAS 

Definition - I Can't Spell Worth a Shit.

Background - While on Rimfire Central's forum, someone asked what the various acronyms meant that posters were using. After posting some of the ones I commonly used, I noticed I had made a spelling error. My first thought was "I can't spell worth a shit," and so I included that ICSWAS acronym as an attempt at humor when I edited my post. To the best of my knowledge, no one has ever used the acronym before me, but of course I could be wrong as I don't constantly patrol the net looking for new words :)

Post edited because ICSWAS.
