What does "port" mean in the Caribbean?

The "port side" of the Caribbean belongs to a joke in the movie. The word pirates of the Caribbean has been changed to "port" in the Caribbean, and port refers to the left leg.

This sentence comes from the movie Pirates of the Caribbean 5, which is a fantasy adventure movie released by Disney Film Company on 20 15. The film mainly tells the story that Captain Jack and his party will look for the Trident, and Captain Teague, Captain Jack's father, holds important information about the Trident. It can be seen that the boat is an indispensable element in this film.

In the film, Lena falls from the gallows in her left leg, and Henry catches her from below. Henry said he held the port side, while karina pointed out sourly that he held the stern and port side (from stern to bow, port side is on the left and starboard side is on the right).

Looking from the bow to the stern, starboard is on the left and port is on the right. In this clip, Henry and Karin vividly compare the place where Karin is being held to the port and stern of a ship.
