A little-known and poorly documented organ located directly between the stomach and rectum that allows partially digested food to bypass the rest of the digestive system. When activated, newly-eaten food will be forcefully expelled before food currently sitting in the GI tract.
The Bypass Valve is typically activated by spicy food, sauerkraut, or bad fast food. The result, inevitably, is explosive diarrhea that will contain either a) foam, b) undigested food bits, c) blood, or d) all of the above.

What you create when you place the mouth of a beverage-bottle whose contents you plan to finish right then under your nose, press it inwards lightly to form a seal, tilt your head back, and then slowly slide the bottle downwards so that its opening gets gradually exposed overtop of your mouth and you can thus guzzle the liquid directly down your throat; the trick is to keep your upper lip pressed against the mouth of the bottle so that you're still partially covering the bottle's mouth, and thus the drink glugs out slowly enough to allow you to swallow it at a comfortable rate until the bottle is empty.
I often get odd looks from others when I employ the "upper-lip valve" method of drinking out of a bottle, but it allows me to both still breathe freely while I'm downing said libation, and also keep from spilling it all over myself, and so I don't really mind being thought of as a bit weird or inelegant.

Amy: "How good is this sticky date pudding?!"
Sarah: "I am loving it but the sticky date valve is really limiting my ability to eat my fill"

the correct spelling of the phrase "foo-foo valve". Reference to the noise when one lets an accidental pass gas "pfoof/pfft", and more obscure but relevant reference to the slang australian (and new zealand) term for a gay man "poof"- as indirectly referring to the anus.

Did you hear that Igor is in hospital? Yep, tried to hurdle a fence and landed awkwardly. Got a fence post right up his Coalman's Valve. The paramedic said it looked like a sore one.
