The One-Eyed Angry Pirate is when you are having sex with a woman doggy-style, and you are about to come, then you pull out and spit on her back so she thinks you came. So she turns around to face you, then you ejactulate in her eye, and kick her in the shin. She will then chase you hopping around on one leg, seeing out of one eye, like a One-eyed Angry Pirate.
Dude: So, My girlfriend turned into a One-Eyed Angry Pirate again.
Dude2: Man, I can’t believe you did that again, you’re such a bastard.
Dude: I know.
