To yank something is to pull it hard and suddenly, in one quick movement. The suddenness is the whole point. If you pull a door, that could be slow and gentle; if you yank a door, it comes at you fast, and often there is a bit of temper or panic or hurry in it.

You yank a weed out of the ground, yank your hand back from a hot pan, yank someone by the arm. It is also a noun: "give it a good yank". English likes to add a small word after it — yank it open, yank it out, yank it off, yank it away — and that little word tells you where the thing went.

The word is informal but not rude; it is fine in speech, in stories, in ordinary writing, but a formal report would probably say "pulled sharply". People also stretch it: a company can yank an advert off television, a coach can yank a player out of the game — pulled out fast, with no gentle explanation.
