Pop-Up

A pop-up is a contextual menu that opens when you right-click on certain objects or areas of your computer screen. For instance, if you right-click on an image on a web page, you are presented with choices to save or print the picture.
A pop-up also refers to a new web browser window that is spawned when you land on certain web pages. Typically, an advertisement opens in the new window.
