english-language expressions that are grammatically wrong or ambiguous

[Juncoph]

why does english have so many bizarre sayings which don't really fit modern colloquial english?

go to bed
welcome home
never mind
add insult to injury
far cry from x

etc

they're different from idioms, where you're making an imaginary example to compare with the contemporary context, so in that regard they have no excuses

I think he's saying that grammatically it should be "go to your bed," similar with "never you mind" or the welcome home one
But I think it's fine considering there are sentences where parts of the sentence are only implied, like "help [me]!"

Adding insult to injury seems fine though. Someone kicks you and calls you a bitch. Makes it a little worse.

also i'm pretty sure the point isn't to compare it to name calling, rather to point out hypocrisy

[Mardalf]

Anyone else see people trying to "sale" something or putting something up "for sell"

It's ridiculous but maybe not exactly on topic, being more a case of ignorance.

The proper is not the concern here since you are talking about colloquialisms which are, by definition, not formal/proper.
Colloquialism - a word or phrase that is not formal or literary, typically one used in ordinary or familiar conversation.
In modern colloquial english, the phrases mentioned in the op are not incorrect.
