At the same time, I was re-entering Army culture after a quarter century. The Army has thousands of official and unofficial acronyms with few rules. One of those rules says that if a three-letter acronym has the letter F in the middle the F is always the same word. So BFR means Big F**king Rock. NFW means No effing Way, and so on.
One day shortly after my re-enlistment my daughter Lisa burst into the house after soccer practice. She was dropping her gear and going to Claire's for dinner. She referred to Claire as her BFF. I wasn't paying full attention to the blond blur that was passing through the house until I heard BFF. I understood that Lisa was saying Claire is her best friend (still is as a matter of fact), but I was surprised she would refer to Claire as her Best effing Friend.
I said, "Lisa, when you say BFF, I get that Claire is your best friend, but is it like the Army acronym?"
The blond blur stopped. She looked at me, smiled when she realized what I was asking and said, "Dad, it's Best Friends Forever! It's not Army."
Glad we cleared that up. Not that it was a BFD.
