look up any word, like tinder bombing:
1) Tie up a girl from behind, be like a pirate and rape her. Fuck her as long as you want, only stop when she lets out a sign of pleasure. Or until you hit the climax.
She will be claimed as your "treasure" then if you cum in her.

2) When a pirate rapes a girl.

3) Someone who is drunk, acting like a pirate then rapes a random chick.
"I just got pirate raped! It felt sooo good, I didnt want to let him know but the pleasure was killing me!"
