If you have a fishing pole, you need a line attached to the pole in order to fish. You need a hook on the end of the line. To put the hook and the line under water, you need a sinker. So, to have everything you need to fish, you need a hook, line, and sinker. The idiom means you need it to be complete.
This is a shortened form of a quotation: "He swallowed it hook, line and sinker" meaning that someone "took the bait" and believed in a falsehood. If a fish swallows the hook, the line, and the lead sinker, it's swallowed everything, so you say this about someone who has been gullible and fell for a prank or joke.
Hook up can mean several things. For example. Hook up could mean that you ran into an old friend and the two of you hooked up for the night. It could also mean that you are going to hook something on a wall and off the floor where it's in the way all the time. It could also mean that you met a lady or a lady met a man and the two of them hooked up for the evening or night.AnswerConnect or link up.
