Override: This occurs when each house of Congress votes on a bill vetoed by the President and secures at least two-thirds majority to pass it despite his disapproval. It’s akin to overriding someone’s decision with group consensus in a team project.
Pocket Veto: This is an indirect veto of a legislative bill by the president or a governor by retaining the bill unsigned until it's too late for it to be dealt with during the legislative session. It’s like ignoring someone’s text message until it's too late to respond.
Line-Item Veto: This allows an executive to reject specific provisions of a bill enacted by a legislature without vetoing the entire bill. It’s like editing out parts of a video you don’t like before posting it online.
