Term of derision about a certain individual who shall remain nameless. When the subject of a social occasion or gathering is mentioned, the individual manages to come up with multiple reasons why they cannot partake. Such excuses are usually comical in nature and in most cases are the result of the limited social aspirations of said individual. The number 40 is in reference to the quantity of excuses used to weasel out of any social event.

The opposite of duct tape.

Like matter and anti-matter, these 2 must never be brought in contact or the universe will be destroyed.

WD Stands for Water Displacement and it took the developers 40 attempts to get a formula which worked. Convair, an aerospace contractor, first used WD-40 to protect the outer skin of the Atlas Missile from rust and corrosion.

Ze Lifeforce. WD 40 is the multipurpose lubricant in a can. It can be purchased in a vast array of sizes, from the small home-use bottle to massive industrial size. Recommended for anything that doesn't move, but should, not recommended for use as a cooking spray. Also handy for fine tuning flame thrower abilities.

Use the WD-40 on the squeaky door

WD-40 was origionally developed by the Rocket Chemicals Company in 1953. The name means Wated Displacement 40 (40 is the formula number). It was first used in air and space applications such as the Atlas Missile. It is primarily made up of various petrolium products and mineral spirits. Just like duct tape, it is a cornerstone of the average man's life. Also like duct tape, it has an uncountable number of uses. It is primarily used to lubricate and clean metal while also preventing corrosion and rust.

WD-40 is easily recognized by its blue and yellow can with the red cap. It comes with a little red straw that is stuck into the nozzle to help direct the spray. Recently, to combat the inconvieniece of the straw, WD-40 released a new design with an attatched straw on a hinge to increase ease of use.
If it is stuck, tight, rusty or dirty, use some WD-40 on it. It is the opposite of duct tape in that it makes things unstuck. Like duct tape, it is cheap and avaliable everywhere. It is a must for the handyman.

Genesis of WD-40 "Water Displacement 40th attempt. Successful" As stated years ago by a representative of the manufacturer on CNBC. Comes directly from the procedural notes of the experimenters and how they referred to the final formula, which indeed does displace and protect against moisture.
Apparently the previous 39 formula attempts were not charted as successful.
City dwellers rely on Duct Tape & WD 40,
ranchers rely on Barbed Wire & Spit.
