Twinn

Used to describe your brother-from-another-mother. Need only be a twin of personality to be a Twinn, but physical depiction is extra credit. The word first came into use in 2005 in an AIM conversation when a mistype of "twin" happened across the chat-box.

Twinn, you should probably look up the meaning of epos also.
