A mail service primarily serving the "just found the invoice due tomorrow under a pile of papers" crowd.
UPS Express: Proudly stepping up to unnecessarily rush important things to important people because you like to procrastinate like a mofo since 1982.

Commonly used in elephant guns these are very poweful rifle rounds commonly used for big game hunting such as elephants, cape buffaloes, rhinos and the like. They have extremey harsh recoil and muzzle blast. The name comes from the powder which is made of nitroglycerin and express indicates the extremely high velocity of the rounds. Currently 700 nitro express is the most powerful of them all.

The Shamu Express is when you sneak into Sea World and go into the whale tank. You sedate the whale and then proceed to fuck it in the blowhole.

My boyfriend and I broke up and got back together 5 times this month. I feel like I'm on the biPolar Express.

A text string pattern matching mechanism. Usually applied to individual lines of text, such as from a simple text file, where the regular expression (sometimes abbreviated as RE) pattern can be used to precisely specify which lines ought to match and which shouldn't. The more complicated REs may look very confusing to people who don't know them, as they look more like a random string of letters and other characters without any obvious meaning.
Commonly they're enclosed between slashes (/like this/), because that's how they were used in many ancient Unix tools. They can also be used for text substitution, for example with the s/ construct. A common operator specifying that a RE will follow is the tilde (~).
The Perl language makes heavy use of regular expressions, and the grep tool also searches by REs. SED and AWK are some older tools also using REs.
REs come in two forms: Basic REs and Extended REs, varying slightly in syntax and possible contructs. Perl extens the Extended REs even further and has defined the standard "Perl Compatible REs" (PCRE).

"some example string" =~ /^s*.*e+.*(?:x.* )?.*?g$/
result: 1 (because the regular expression between the // matches the string)

Originated by teens without a car or means of transportation. It basicly means that if you go anywhere, you get there by foot; hence the term nike express.
All of my friends forgot to pick me up on their way to the mall, so I caught the nike express. see walk
