nonniversary 

The day that would have been the anniversary of a relationship that failed.

Michelle: I would have been married to Oscar 12 years today... if he hadn't been a total cheating, lying douchebag that I divorced.
Amber: Happy nonniversary.

the great thing about a noniversary is you don't have to spend any cash, unlike an anniversary

noniversary 

how non-couples (aka friends with benefits) celebrate the passage of time

Me: For our one-year noniversary, Ben took me back to Charlie's where we had our first date.

Friend: Aww...how sweet.

Me: I know, right. But he still isn't willing to update his FaceBook status.

Noniversary 

What might have been an anniversary had the relationship worked out, but it didn't and you either want to seem cool about it or bitchy. Either way works depending how you use it.

(after breaking up)
Kate: you know what today is right?
Nick: uhh....
Kate: the day we started dating silly!
Nick: right, which we aren't anymore...
Kate: yeah....
Nick: happy noniversary?
Kate: awhhh <3 i regifted the bear you got me by the way.
