1337 hour 

1337 hour (pronounced Leet Hour) is the time when everyone should stop what they are doing and do something elite. Leet hour is 1:37PM which originates from 1337 or 13:37 military time. It's important to note that 1337 hour is not actually an hour but rather a minute, from 13:37 to 13:38. It is referred to as 1337 hour because actions performed during that minute are more epic than normal actions that actually take hours.

Okay, 1337 is a good subject to talk about. The first thing I would like to clear up is that chatspeak and 1337 are NOT the same thing. Some lazy morons merge 1337 and chatspeak together, soon creating the popular belief that 1337 and chatspeak are the same thing.

Okay, so what /is/ 1337 in the first place? 1337 means Elite. The point of 1337 is to replace all the letters with symbols, and is quite fun to play with. 1337 was first created by some people would wanted to talk in a forum without any outsiders barging in. Some outsiders may have figured out the language and started using it as well. Eventually, 1337 became famous all over the internet. The original use of 1337 is hardly practiced any more, but it survives because many of peope use it for fun.
