For those who don't speak 1337, HaXoR, or otherwise known as leetspeak is what people would call the "Language of the Internet". Some of you who go on the internet to use Facebook and YouTube may have no idea what this is, but to those who actually have explored have grown accustomed to this silly language. For those who haven't translated 1337, it translates to "leet", which stands for "Elite [speak]", which implies only those who know their way around the Internet know how to read and even write in 1337. Note though that leet speak is not chat speak, which is what a lot of people use when texting or IM'ing. This is purely for a further enjoyment of the Internet.
Each letter in the alphabet can pretty much be replaced with a symbol or a number or even another letter. For example, simply conversions are from "A" to "@" or "E" to "3", but that doesn't necessarily make it the only option. You could use "4" for "A" and "€" for "E" which can lead to endless possibilities. Words can also be skewed and shortened. The word "the" is usually written as "teh" and short words like "are" and "you" are almost always replaced by "R" and "U". Sometimes, words don't even have to have special characters, you can write them using just letters and numbers. 0nly n00bz liek teh speshul ch4c4t3rz. For really intense leet speak, letters can be made out of multiple characters, usually using slashes. Letters and phrases are constantly added to the end of words are well, such as -z, -age , and other nonsense.

This can be really hard to read.
But no worries if you think you can't handle that, it's understandable. There is always a more casual side to leetspeak, usually used in memes which are inside internet jokes, that don't require as much use of characters. This "dialect" is a mixture of 1337 speak and chat speak is somewhat considered "weaksauce" by the "leet" of the internet but by some it is absolutely fun to use.

At last, I leave you with one last piece of leet speak (it's really easy), try to decipher it.
