Re: hyena lacuna checklist marvel. "Could someone provide the story please?"
I know it sounds like a lipstick, but it actually makes some kind of sense.
Anatomically, a "lacuna" is "an empty space or a missing part".
Metaphorically, "lacuna" is missing grey matter, or simply "ignorance".
"Hyena" rhymes with "lacuna" but it also conjures up "laughing hyena".
Hyenas don't actually laugh. They are too empty-handed to laugh. And some people lacking in grey matter have more in common with hyenas than their laugh.
Hence, "hyena lacuna".
It is not a compliment.
The term "hyena lacuna" may spring to mind the next time someone sends you a reply beginning "LOL", particularly if you haven't said anything funny.
"checklist marvel" is just some archive somewhere, I suspect.
