Assassiversary (assassination + anniversary)

An “assassiversary” (assassination + anniversary) is the anniversary of an assassination. For example, November 22nd is the “assassiversary” of the 1963 assassination of John F. Kennedy. On May 1, 2012, Comedy Central’s The Daily Show said that it was the one-year “assassiversary” of the death of Osama bin Laden.
 
The term “assassiversary” has been cited in print since at least 2005.

Happy JFK assassiversary
I visited Dealey Plaza and the Schoolbook Depository museum in Dallas in the summer of 1994, when I had a splitting headache and possibly food poisoning. An unforgettable experience nonetheless.

The second night of the fourth quarter was a back-and-forth affair. After the departure of Peel-Out at shortly after 7:30, the remaining quartet played more than an hour before anyone else walked the poker walk of shame.
