Give Up or Give it Up

[Cj_b]

I recently heard someone say "Ok, I give it up" - after failing to print something. I thought the right expression would be " Ok, I give up" but they disagree. If "I give it up" is right, whats the reason for this?

"Okay, I give up," is one correct way to say it.

We can also say, "Okay, give it up." When we say that, it is as if were were talking to ourselves and giving ourselves a command.
