Why is "Hands off!" incorect? I find it unlikely someone would exlaim just "Hands!"
Em, in which situations can you use this phrase? When you're a policeman and you're chasing a robber?
As alex_tv80 said it's really something like "Take your hands off!" :) When you don't want someone to touch something
So, I translated this as "arms" and it was accepted. Why, if it is an idiom for "take your hands off?" Is there also an idiomatic understanding of this that uses "arms"? If so, could someone please explain it here?
