Don't come on in!

Is the above negative imperative sentence acceptable?

Thanks a lot for your reply.

Unfortunately not. We would simply say;

Don't come in!

Cheers

The particle "on" with verbs of motion is generally used to offer encouragement to act. With a negative, a contradictory message results, so the sentence is really not possible (as already mentioned).

1. Hurry up.

2. Don't hurry up.

3. Stand up.

4. Don't stand up.

According to my knowledge, sentences #1 and #3 are acceptable; sentence #2 is not acceptable. Am I right?

Can anyone tell me if sentence #4 is acceptable? Thank you very much for your reply.
I too feel #2 is somehow incorrect. Maybe it is because "up" functions as an emphasizer of "hurry". But #4 doesn't seem wrong. I think "up" here is not an emphasizer but a usual manner adverb to describe the state of "stand".

I agree with Paco. "Don't hurry up", used to assure someone that there is no need to hurry, i.e., the equivalent of "Don't hurry", doesn't work.
However, in a tone of exasperation, used as the negation of a previous similar utterance, it will work.

-- Hurry up! Hurry up! You're going to be late. Come on! Get going!
-- (No reaction. Pause. Still no reaction.) (Silence.)
-- OK. Don't hurry up. See if I care. When you show up late, it'll be your own fault.

Here it is not a sincere use of "Don't hurry", but a sarcastic "You're not obeying me".
