FIL

What does FIL stand for?

Father-in-law

The acronym FIL stands for "father-in-law." When a person gets married, their spouse's father becomes their father-in-law. So, if someone asks you about your FIL, they're likely asking about your spouse's father.

Pop culture has taught men, especially, that they should be intimidated by their father-in-law. However, many men get along well with their FILs, with some even becoming bros.

Example

"Thankfully, I get along with my FIL pretty well."
"MBN, I think mine's insane."

If your FIL gives you a sensible chuckle, he likely thinks you're alright
