e-mailsn
When you and a friend are replying to e-mails at such speed it looks like the two of you are chatting on msn. Must happen accidentally, at the risk of being a bona fide nerd.
re:-party
Derived from the French ''repartie'', meaning answer. Simultaneous responses from all the recipients of an e-mail to all the others. These replies are then opened and commented upon by the others. Two days later you open your inbox and it looks like a freakin' zoo has taken over your e-mail.
