look up any word, like bukkake:
 
1.
Men's shorts that go down to the middle of the calf. Black. Made of material that does NOT unravel when cut, therefore, the bottoms are cut all zig zag to look rugged, but not unraveled. Also, made of material that sheds water rather than soaks it up. Good swim trunks and all round summer wear.

A skull & cross bones on the pocket is a nice touch. Pirates are very untrusting, so the pocket MUST be on the FRONT of the leg (NO side or back pockets) and is usually zippered for security (there are MODERN pirates you know).

2.
Pants that have been cut, branded or otherwise marked to appear like they are well worn, unwashed, ratty and have the overall look of those a pirate would wear.

Often worn by modernday Pirates who follow the Piratecore lifestyle
Josh - "Dude, you should get some new pants. Those are nasty"
Jack - "Calm down man. They're my pirate pants."

also: my pirate pants have shredded cuffs, scraped knees and an iron-on jolly roger on the ass

3.
stupid looking pants that are tight at the waist and get very big at the end, making the wearing , who is usually (and hopefully) a girl, look extremly stupid.
Lindsay-hey, do you like my new pants.

Connor-No, those pirate pants make you look like the hideous offspring of liberachi and blackbeard.
