Opposite of the 'Bros before Hoes' rule.
A single guy who chooses to go and hang out with female company or other event attended by women rather than hang out somewhere with his male only friends.
This is done in the hopes of scoring or to put in the legwork so he
may pick up a woman at a later time.
So called presumably, because you are out to score some
booty.
A guy who hangs out with his established
girlfriend/wife over his friends doesn't apply and is still pussy whipped.
John:
Hey Nick, you gonna join the boys tonight for some Halo?
Nick: Nah man, I'm invoking the
Pirate Code.
John: Whats On?
Nick: Stephanie from
work is having her birthday at the pub, I'm gonna drink bourbon and hit on one of her friends.
John: Good luck man.
