A grouping of alphanumeric characters meant to convey some sort of a message, but often not closely enough resembling an actual language to be easily read and understood.
Letter piles are commonly found on the internet in instant messages, emails, forums, blog comments, answers on Q&A sites, and even some definitions on Urban Dictionary. This is not to be confused with 1337 sp33k, which is purposely obfuscated, although letter piles often contain 1337 sp33k.
