Yo, Peace Out. Used when closing an email or IM chat to say good bye. Typically used in male-to-male communications.

The word yo with a "p" in it. Originally a typo resulting from the proximity of the letters "o" and "p" on the keyboard, and the ease with which such keys can mistakenly be struck simultaneously when solely one key was intended, "ypo" is now considered the more proper way to greet someone whilst chatting on AIM. See also pwnt.
