Ejaculating on someone's eye while they sleep. When they wake up, idealy, the ejaculation will have dried up, making it impossible to open or see out of this eye. Just like an eyepatch.
Jill could not stop herself from saying "Arr, shiver me timbers" after her boyfriend gave her the ol' Pirate Eye the night before.
At the climax of oral stimulation, a man ejacualtes into his partner's eye, rendering the partner blind in oneeye. Comes from the traditional look of a pirate wearing an eye-patch.
Stacy didn't talk to Andrew for three weeks after the 'pirate eye' episode.
