I’m taking it at face value that old earth figures of speech and idioms would be problematic on a TAS bridge with the nomaly going on, they addressed that by the cat person responding that “there is more than one way to disembowel a human”, we wouldn’t like people casually throwing that around. It’s also tongue in cheek as illustrated by the knickerstonians and the ship blowing up. It’s meant to be silly.
The tapestry of star trek (and science fiction) has always included silly and over the top alongside the serious, thought provoking and intelligent.
Cornering the star trek parody and comedy market with their own product is genius btw. Like how Elvis’s manager sold “I hate Elvis” shirts.
