A Revoke Invitation Ritual was a basic ritual intended to revoke the invitation to vampires. First seen in "Passion", it was used to revoke Angelus' invitation from Cordelia Chase' car, Willow Rosenberg's room, Buffy Summers' home and Rupert Giles' apartment. Buffy later had Willow and Tara Maclay revoke the invitations of Dracula, Harmony Kendall and Spike into her home. The vampire can be reinvited with no complications except the ritual would have to be performed again if the invitation had to be rerevoked.
