How do you use "come it"?

Question

How do you use "come it"?
I am not sure.
please give me some example sentences.
Do you often use it?
is it casual?
and also what does mean it exactly?
Thanks

Answer 1

You may mean 'come off it'... I can't think of a context in which I'd say 'come it'.
When someone is being unreasonable, you say, 'oh, come off it!' My mom says it all the time. I'd say it's rather casual, yeah. You wouldn't want to use it during a job interview.
I guess I'd translate it as "stop doing that".

EDIT: Temptingbutnothanks has a good point. I'll elaborate on it for you.

As an obligation:
- "Commit yourself to it" means to stand by it, be persistent, and don't give up. More often you'll hear, "Make a commitment," which means the same thing.
-"He was committed" can mean that he was put in an metal institution or that once was obligated to a project/thing/person.
-"He committed a crime" means that he performed an intentional action, in this case a crime. It usually is accompanied by something negative: "He committed adultery, murder, manslaughter..."

'Commit' can be used in any context: formal, casual, it doesn't really matter; it's a pretty common word.

Answer 2

I don't believe that is a real term. perhaps it is supposed to be "commit" which has many many uses.
