An acronym for the tragic and debilitating medical condition- Obsessive Compulsive Calendar Invite Dickhead. Sufferers are known to infuriatingly and incessantly send google calendar invites to acquaintances for even the most trivial of scheduled appointments, thus clogging up the unwilling recipients email, calendar and life. The only proven treatment is for the perpetrator to be euthanised.
