Unvite Edit Meaning

1.

Sending an invitation very last minute with the hope invitee will already have plans. Unvites are used when you do not want someone to attend but NOT sending them an invitation would be rude.

An Unvite will say something like this:

"Sorry such short notice; I'll understand if you can't make it."

See invite, party, wedding

2.

To un-invite somebody. After you have given an invitation you change your mind and go ahead and un-invite them. Ref: from the Seinfeld episode

I got an unvite. I've just been unvited!
