The Abbreviation Has Another Function

(I have a friend who has been home-schooled from kindergarten on, so she tends to say things without knowing what ‘alternate meaning’ there might be. She just got a laptop and we are talking about it. Due to our religious upbringing neither of us cuss, but I went through public school so am more likely to catch innuendos.)

Friend: “Yeah, so if you press the ‘effin’ key.”

(I look over and see her pointing to the ‘Function’ key, labeled FN.)

Me: “Oh, the function key.”

Friend: “Yeah, the ‘effin’ key.

Me: “Please… please call it the function key. The ‘effin’ key just sounds… weird.”
