Pi is an irrational number (meaning the digits never end or have a repeating pattern) that is the ratio of the circumference of a circle to its diameter...this ratio is a constant for any circle, regardless of size.

The first 100 digits for pi is equal to 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 ...

PIED does mean Porn-Induced Erectile Dysfunction but it does not mainly affect virgins per your definition.

I have been a sex educator for 45 years+ and this is rampant for any males who get a significant portion of sexual gratification from porn. And then when the opportunity presents itself, they come up "short".

Used in a sentence: She started dating this guy who had been single and celibate for 5 years who spends hours watching porn every night and now can't get it up for her because he has PIED.

pi is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius.

pi is an irrational number, which means that its value cannot be expressed exactly as a fraction m/n, where m and n are integers. Consequently, its decimal representation never ends or repeats. It is also a transcendental number, which implies, among other things, that no finite sequence of algebraic operations on integers (powers, roots, sums, etc.) can be equal to its value.

The current record for the number of computed digits of pi is more than 2.5 trillion (10^12) digits. Completed on Aug 24, 2009, in Japan by the University of Tsukuba, it took the supercomputer system T2K Tsukuba almost 74 hours to calculate the 2‚576‚980‚370‚000 digits of pi.

I would paste the record number of pi here but it would take up over 2.5 terabytes of space (assuming each number is 1 byte) and I don't think Urban dictionary would appreciate that.

the reason the definition is titled under "pi !" instead of "pi" is cause all those fuckfaces posting definitions under "pi" copy/pasted a whole bunch of fucking numbers of pi that no one gives a shit about, and the long ass numbers have completely assfucked the whole page so the text scrolls sideways and you cant read anyone elses definitions

When a character does something that they should not be able to do, it is called PIS. For example, Wolverine beating the Hulk, or Superman turning back time)
