What is AOLese?

AOLese consists of slang that users of the AOL Internet service have developed that were once specific only to the AOL service itself. Many AOLese terms originated with the purpose of saving keystrokes in AOL chat rooms and Instant Messages, (for example, "IM" for "Instant Message", "YGM" for "You've Got Mail", "YGP" for "You've Got Pictures", etc.).
