Why? In which situations would this be actually ambiguous and, in that set, in which situations would the disambiguation actually be necessary for some real reason?

"Inflammable"

If we come up with something in this thread, I'll be here to corrupt its meaning by misusing it.

Why? Does fungus need a reason to give you jock itch?

Aliterally?

Actually, though.

"Exactly."

Or just stop widely accepting the dual meaning.

I would argue that, uses of literally, in the literal sense, in common language, is rarely used, any more. Mostly because, If you have to add "believe me" at the end of your sentence, it makes you seem sus. And "literally", in common language, is usually added to the end, in the same way, the sarcastic, and facetious, presentations use. So we've adopted different signifiers, mostly, anyway. People usually say, "you are not going to believe what happened to me today ". Even the sarcastic etc uses are dying out, in a time when, extreme positions aren't, easily taken at face value for being over the top, or, easily definable as sarcasm etc, which is what sarcasm relies heavily on. I think, all the extreme stuff going on, is making it almost impossible to even use literally, in almost either application. I'm sad! It's such a fun word to say.

Nope.

Actually…. Oh wait that one is almost on the list too by now.
