Acronym for: Fucking Spell Check Strikes Again. When typing on phones and the auto-correct / spell-checker kicks in and suggests outlandish words that you most likely wont' see until your post/text/twee is out there for the whole world to see.
"Can you pick me up later from LAXATIVES after I fly in" "Wait. FSCSA! I meant to type 'Can you pick me up from LAX after I fly in?'".
