look up any word, like bootylicious:
1. Billion
I believe in the UK a "billion" means a million millions (e.g. 10^12 rather than 10^9)
Pretty self-explanatory.

2. billion
America and most other non-british-colonized countries (let's not debate about that): 1,000,000,000
: 1 thousand Million

Australia, The Uk etc. : 1,000,000,000,000

3. billion
In English speaking countries means 10^9, in all other languages and countries except Brazilian Portuguese means 10^12. This is because English speaking nations use the short scale, where new notation is used when multiplied by 1000, rather than the long scale where its when multiplied by a million.
In English speaking countries, a billion times a thousand is a trillion. In non English speaking countries, a billion times a thousand is a billiard, which times a thousand THEN becomes a trillion.
4. billion
Most everywhere: One thousand millions;
1,000,000,000

Also meant to exaggerate.
I've seen that movie a billion times.

5. Billion
A derisive term for computer geeks who proffer 3 fundamental beliefs:
1) Microsoft can do no wrong and is right and admirable to pursue dominance by any means necessary.
2) There are NO other viable computing/development platforms.
3) That successful marketing by Microsoft has not influenced their computing/technology choices.

The term "Billion" is a combination of 'Bill' (Bill Gates, Microsoft co-founder and it's most recognizable face) and 'Legion'. So, "billion" = "Bill's Legions." Also, it's a play on the idea that such people eagerly add billions of dollars to Mr. Gates' fortunes.
"His anti-Open Source tirade was spoken like a true Billion."
"My life as a Billion has not been without it's share of viruses and installation headaches."
"No self-respecting Billion would be caught dead using a Macintosh."
