f/o

Stands for "fictional other" in replacement of the term "significant other." Almost exclusively used by Kinstagram users who have a delusional belief that a fictional character is in love with them.

f/c

f/c means face check. In League it is used when you need to get vision and you don't have wards. So you just come there and check it (by your body) if its clear.

Don't f/c or you will die!
Make that f/c for us.
