A new term - bitchuary

bitchuary [bich'-yoo-a-ree] n. an announcement of the death of a public figure, containing a remark that can be construed as humorously insensitive or uncomplimentary. [Cf. bitchy and obituary.]

Example:

Evel Knievel died today at the age of 69. Fans across the globe are launching motorcycles from ramps and crash-landing in his memory.
