The 'colorful metaphors' make no sense
It's funny, how Kirk tries to teach Spock how to use 'colorful language', but it comes off as if none of them have ever used the word 'hell' in a way to emphasize something.
This would work, if it weren't for the scene, where Bones actually uses the term 'the hell' BEFORE the timewarp, in the exact, correct manner!
I copied this from some website, so I am not sure if it's 100% correct, but according to my memory, it's close enough in any case - Bones says something like this to Kirk:
"You're proposing that we go backwards in time, find humpback whales, then bring them forward in time, drop 'em off and hope THE HELL they tell this probe what to go do with itself!"
(Emphasis mine)
Why would he know of all this colorful language, if none of the others know about it, and why doesn't Kirk wonder about the usage of this peculiar venacular, if he is completely alien to it?
If Bones can already know how to use 'the hell' correctly, why doesn't Kirk and/or Spock? I know Spock is a bit 'out of it', but he seems to still be intelligent and able to know things, so why not this?
Too bad even this movie makes no sense, as I rather like it otherwise.
