One-Way-Valve

Refers to the sphincter muscle in the rectum. Usually refers to the out-going flow of the body of any material.

When drinking heavily on Spring break in Key West, your friends are heard to say "Don't let them puncture your one-way-valve!"

pound one out

To play with yourself. When you only have a few minutes to pull it off.

Jason told me he had a few minutes to pound one out before we went to grab a beer.

We Are One in Pi.

When math geeks are connected to each other by their shared love for arguably the most beautiful constant in mathematics: π’s beauty, ubiquity, and utility never fail to bring and bond them together.

Just as a number of white racists and supremacists are united by the xenophobic policies of Donald J. Trump, so a number of recreational mathematicians are drawn by the occurrence or presence of pi in the least unexpected places, who love telling the non-math people: “We are one in pi.”
