What does "around" mean here? Can I omit it?

Rebecca

"Order someone around" is an idiom that refers to telling someone what to do in a rude, inconsiderate way, as though you have authority over them. "Around" in this idiom implies that the person being "ordered" is busy completing tasks. Because this is an idiom, "around" can not be omitted. Ex: I order my little sister around because I'm older. Ex: I'm tired of my boss ordering me around constantly.
