Web 2.0

A buzzword used by dullards to seem hip and "in" on "latest" technology, in hopes that no one will be perceptive enough to see that what's "Web 2.0" isn't new at all, but rather a catch-all term for websites that give people imagined self-importance by letting them comment on and share content with other equally moronic readers.

OMG this website is so Web 2.0! Check it out there's a button to post this to my facebook, myspace, and twitter! Now all my friends will see how hip I am and maybe someone will finally love me!

2.0

(Read: two point oh | two point zero)

Marketing catchphrase/buzzword than, when attached to a name, implies an "improved" or "superior" product than it's predicesor.

When used in comparisons like ' A is B 2.0" ,' it's like saying "B" is like "A" only "better."

SUVs are station wagons 2.0.

George Bush and Osama bin Laden think they're Jesus Christ 2.0.

a laugh and a 0.5

Internet/IM speak for a laugh and a half, meaning something is mildly amusing. Substitute for a higher fractional number if the situation calls for it (i.e. a laugh and a 0.7).

Person 1: Did you see yesterday's episode of The Daily Show? It really was a laugh and a 0.5.

Person 2 appears to be offline.

5.0

In 1982, Ford reintroduced a high-performance Mustang GT which opened the door for an entirely new era of the muscle car. Wringing a then-respectable 157 hp from its "5.0" (actually 4.94 L, 302 in³) Windsor V8.

The "5.0" Mustangs, cars that gave birth to an entire aftermarket performance industry, continue to remain extremely popular today.

Pronounced "five point oh."
