upper-lip valve

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.

pfoofer valve

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.

he nearly blew his pfoofer valve

lapping valves

Lapping valves is how people attempt to save money on a valve job and kill power at the same time.

I'm to cheap to go to a machine shop so I'm lapping valves myself.

Knuter Valve

The male valve that controls urine flow.

After Ed turned 40 and his knuter valve stopped working properly, he would think he was done urinating and would dribble pee on the front of his pants.
