I prolly first saw "shotty" on my 'puter a few years ago.
Words such as these make me gag. They sound like kindergarten slang. Nobody in the COMPUTER industry calls them 'puters, except in Tom Clancy novels. Lots of obscene and foul names but not that cutesy one.
Same with "shotty." I grew up with firearms and hunting pheasants and ducks and never heard that term used except by newbies on gun forums. "Shot ty" is two syllables, same as "shot gun". It is one less letter. How is this more handy to use than the proper word except to be cute?
"Prolly" was invented just to be annoying. Stop it. Please.
