The expression "wave off" is commonly used when talking about stopping or canceling something. For example, if a plane is trying to land but the runway is not clear, the air traffic controller might "wave off" the plane, meaning they tell the pilot to abort the landing and try again later. The expression can also be used in social situations. If someone is trying to give you unwanted attention, you might "wave them off" by politely telling them you're not interested in talking or spending time with them. Overall, "wave off" can be used in situations where you want to indicate that something needs to stop or be canceled, particularly in cases where safety or boundaries are at risk.
