To remove someone or something from a particular place or area, especially roughly or dismissively, typically because it is a nuisance or is going to be discarded. A noun or pronoun can be used between "cart" and "off." The police carted off the burglar after they caught him fleeing the scene of the crime. I don't need half the junk that's in my new office, so I'm going to ask one of the cleaning guys to cart it all off.
