5. Modern slang
If something is “salty,” that means you put too much salt on it. That is it. End of story. Any other definition is gibberish, pure and simple. Listen, we get it, every generation has its own unique slang. But we’ll never get used to people saying “LOL” when they mean to say something is funny. You’re either laughing or you’re not; describing laughter with a slang acronym is not the same thing as a genuine guffaw.
