A "fun fact" refers to a piece of information that might not be widely known.
Though, the "fun" in "fun fact" is often widely debatable.
Indeed, more often than not, people find or are told a "fun fact" about anything from an animal species to a famous celebrity which might make them want to cry or even throw up.
A recent Redditor was curious to hear fun facts people know which are, in fact, quite the opposite of "fun", leading them to ask:
"What is a NOT fun fact?"

someone erection GIFGiphyWhen sharing a "fun fact" with a friend, it might be worthwhile to think about the information you're about to share.
And whether or not it is, in fact, "fun".
Instead, maybe share a tidbit, or "info"?
Even if neither roll of the tongue quite as easily...
