Anniversarize 

Wanky corporate term used to celebrate meaningless events on a yearly basis rather than letting them die their deserved mundane death from international history.

Corp type: I need to anniversarize this trade plan.

Replier: Grow a pair, you cock.

The yearly recurrence of the date of that one became a vegetarian. Also known as a vegeversary.
