A meme that originated on a 4chan thread around 2005 when someone replied to a post that stated "Post ending in 'X' (some number) will become a meme." This anonymous person typed the random text “fdsfgs” (probably by tapping the keyboard randomly with their left hand) and hit Enter and, through sheer dumb luck, earned a GET (their post number happened to match the OP request.) Everyone in the thread declared that a new MEME had been born. Someone put the phrase on a picture of Wolf Blitzer – and the rest...is history.

You could either say "figgis-fiddis" or "F-G-S-F-D-S", but however you say it, it is the one word that makes no sense whatsoever at all. It all started when someone on 4chan replied to a post with "fgsfds". Oryan (a 4chan user) soon shopped the phrase into a pic of some old dude (talk show host, probably) and now everyone on /b/ posts it. When somebody confuses you by saying something that makes no sense, simply say "fgsfds".

used to explain something you know nothing about or to confuse others into submission.

fgsfds is a random string produced by typing random letters with your left hand on a standard QWERTY keyboard. The reason people use there left hand is they (usually) have a mouse in the right hand.

A random character string which, through its slyness and intelligence, somehow managed to get past Urban Dictionary's screeners and now has several definitions.
