non-deterministic polynomial time

The set of the most difficult problems in Mathematics, solvable in polynomial time only by a non-deterministic turing machine, but verifiable in polynomial time. In mathematics and computer science is shortened to np. Of course, the editors of UD would rather publish BULLSHIT or several thousand entries for George Bush than something having to do with math. Also, why won't they publish "S4R" is a perfectly acceptable definition.

Rule number 5 + Rule number 10 guys. Seriously. I'm an editor too.

Aaron: Did you know the editors of UD don't actually follow rules 5 and 10?
Mike: Yeah, they turned down my definition for "np", y'know, its short for "Non-deterministic Polynomial time".
James: Yeah, and then the go and publish shit like "S.C.L.I.D". Apparently technical terms for guns are fine, but not in Math.
Aaron: Yeah, seriousy uncouth.
Mike: HOLLA!

Power Couple

A relationship between two people who are equally as cool as each other. They are as individually awesome and fun to be around as they are when they are together.

Neither one depends on the other for their feelings of self worth- they know in their heart that they are just as valuable to the world as the other. Good looking, optimistic, and sparks a light in the world that people recognize that goes beyond a normal relationship.

In a power couple, if one person is flawed, the other person makes up for their weaknesses in strength. Together they are the epitome of what anyone would desire in a relationship. They encourage goodness in the world and make it a better place by being together.

I'm a fan of those two, they are such a power couple, the epitome of what anyone would want in a relationship.

I am envious of them because they are a power couple.

Shackteâu

A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
In use:

Shackteâu - We thought it was an abandoned shed until the realtor called it a rare alpine Shackteâu with unobstructed views and listed it for $2 million.
