Known as the "marriage number" by the Pythagoreans, as it is the sum of the first even, female number, 2, and the first odd, male number 3.
The Pythagorean Theorem when applied to a 3-4-5 right triangle is sometimes called the "Theorem of the Bride": the sides 3 and 4 are linked with the male and female, respectively, and the hypotenuse, 5, with the offspring.

The number that shalt not be counted.
The number after 4 and before 6.
Example of 5...
BROTHER: And the Lord spake, saying, 'First shalt thou take out the Holy Pin. Then, shalt thou count to three. No more. No less. Three shalt be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, nor either count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached, then, lobbest thou thy Holy Hand Grenade of Antioch towards thy foe, who, being naughty in My sight, shall snuff it.'
(Amens)
ARTHUR: Right! One! Two! Five!"

5 is an elite, nerdy way of saying "LOL" See 120.

LOL means "Laughing out loud" and is a common acronym used in chatting everywhere.

LOL (or lol), written in 1337 is 101.
101 in binary is equal to 5 in decimal.

So, LOL = 5

The shortest form of the hugely popular expression "Laughing Out Loud". The evolution from "Laughing Out Loud" to the expression "5" is as shown here:

1. Laughing Out Loud - (Original)
2. lol - (Original -> Acronym)
3. 101 - (Acronym -> 1337 Acronym)
4. 5 - (Binary -> Decimal)

By using "5" instead of "lol", 1337 typists save 66% of their time, thus the need for the expression "5".

Typically a situation that warrants a "5" is funnier than a situation in which "lol" will suffice.
