Despite what many people think, leet speak is not when you make letters with non-letter characters, like

| /\/\ |_33+ 2 |)00|)!!!

Though the non-letter characters used to make letters method is used occasionally, it is primarily made up of numbers acting as letters, like so.

y0 j00!!111 u c m3 0wnz0rz dat n00b v3r1ly ?? lolololololololo

Note that j00 is often used in place of "you" and many words end with a 0rz or a z. Also, letters aren't ALWAYS used, just when someone feels like being "l337". Leet Speak originated as a way for getting vulgar words (such as "u r fuxx0rz d00d!!) through filters in chat rooms and games.

a completely retarded program, utilized by people who are either too stupid, or too lazy, to figure out how to replace letters with numbers and other characters found on a keyboard
hey guys, instead of taking 2 seconds to figure out which numbers look like which letters, i'm going to google "leet speak generator" and spend unnecessary time and bandwidth looking for a completely un-needed program.
