an acronym standing for "Fingers Crossed For Snow," showing one's wishes for frozen precipitation to delay or cancel school, but without jinxing the possibility of such an occurrence.
After slapping the kid for saying the S-word (snow), I told him to say fcfs instead, to not jinx our chances for a snow day.

People tend to use this on social media, like Instagram, Twitter & Facebook. "FCF" means "Female Crush Friday"

Food crush Friday. Similar to wcw (woman crush Wednesday) and mcm (man crush Monday). You pick a food that you love and post a picture of it on a social media site with FCF somewhere in the caption or title.
