Noun.
A conversation exclusively held
via e-mail, often occurring in real-time.
One user may refresh his inbox repeatedly waiting for a reply to continue the conversation.
Gmail and Gchat blur the distinction between IMing and e-mailing noticeably.
"
Hey, listen, I really can't make this a mailversation. You're clogging up my Hotmail."
"I had a
hot mailversation with Susan last night: you should see all the dirty pics she
e-mailed me!"
