A recurring theme associated with the word 'pop' is that of something quick or temporary.
If you say that you will 'pop over' to a place rather than visit it, 'pop round' to see somebody rather than meet up with them, or 'pop out' somewhere rather than go out, you are making it clear that your outing or trip is intended to be brief and short-lived.
Similarly, if you 'pop open' something rather than keep it open, 'pop off' something rather than take it off, 'pop' something on a surface rather than leave it there, you are again implying that the action is intended to be quick and temporary.
Most of its uses tend to be in a social context, but it can also be used informally in a professional one. You could 'pop an email' to a co-worker, for example, or 'pop in' to see your boss.
As the video shows, 'pop' can also be used in relation to the sound something makes, like 'pop a cork,' and 'pop a balloon,' as a shortened version of the word 'popular,' and to describe something that is striking and stands out.
