British Open

Bare assed fart in mouth that results in tainting the teeth from an unexpected squirt.

Dude...I really liked this girl but can't be around her anymore now that I gave her a British Open. Why would she risk asking me to buck in her mouth??

Open Backpack

Meaning that you can see someone's butt crack or underwear slightly as a person is bending over similar to the zipper of a backpack being slightly open.

(Emily bends down to grab books) Me: Hey Emily you've got an open backpack
Emily: Did you notice my new Victoria's Secret thong?
Me: No I was just looking at your crack.
Emily: You're an asshole.
Me: LOL get it?

PM open

For men: a thirsty call for noods. Like a baboon makes its butt more red to attract a mate. The Kik male uses “PM open” in their username and usually a torso to try and lure women in for the noodles.
For women: a risky move on Kik. 83% of women with “PM open” are actually males (see above) which make the other 17% just wanting some deep.

His username said PM open hoping someone would slide.
