Person saying "I literally haven't eaten for months" is literally asking me to tear a new one to him/her...
That was a joke, I am not that much of a grammar-nazi...
But I do dislike inaccuracy of language, thought I can live with it (I have to). Actually, even I use knowingly (read: I don't bother to polish every word and concept for an eternity) language in a wrong way with things that are not important. Or as a form of joking. But using constantly misleading, and even totally wrong concepts,
and not even caring of it... No, no, no, and one more time, no...
Another thing I dislike, is that in work, during morning meetings, when they share tasks between people, they ask "Do you want to do this?" Nope... I
can do it. I
have time to do it. I
have resources to do it. I
know how to do it. But it is very unlikely that I
want to do anything that is just part of my work instead being in my actual field of interest...
Slang words are introduced and do tend to evolve languages exponentially more than educated scholars revise or introduce new terminology in any official capacity. It's because of larger and larger groups of uneducated people using a language while having no clue that specific terminology already exists for what they want to express/say.
Slang is also used as a form of secret language. To make distinction between cultures of different generations, or social circles.
Thought probably not that much these days, but in my country the slang they spoke hundred years ago actually was like a different language, partly based on euphemisms and partly based on loan words even for most basic things that everyone definitely knew the "right and proper words".
Cherokee has almost zero ambiguity. You have to construct your sentences so accurately that there really is only one meaning. If you want to lie in Cherokee, you can't manipulate the words to have multiple meanings. You have to tell a blatent lie.
Why on Earth aren't
all languages that accurate? (I know, I know, because people want to be able to get away with lying. Sigh.)
Now I want to be Cherokee...
