The antonym of the term "lay on line" is "remove from line". It signifies the act of taking something out of the line or queue. To remove or delete something from a lineup or lineup of tasks is a way to undo an action that has been previously established. For instance, if someone realizes that they have included an item in a list or queue by mistake, the act of removing it from that list is the antonym of "laying it on line". Similarly, if something was accidentally added to an online shopping cart, removing it from the cart would be an antonym to "laying it on line".
