cosmically funny

When something is funny in a way that only a passive observer to the universe would find funny. Usually out of irony or blatant injustice, and often as a result of tradgedy or something that would almost never be considered traditionally funny.

Can also be used to describe something as "funny in a cosmic sort of way"

Did you hear about that guy who got hit by a firetruck while he was on fire?

Yeah, that was really tragic, but honestly cosmically funny.
