To retcon a character in a work and make them represent a minority community of the creator’s choice all along, even if it wasn’t mentioned at all in the source material.
Named after the character Prof. Dumbledore from the Harry Potter series, when author JK Rowling announced that Dumbledore is gay without explicitly stating or hinting it in the source text.
Blizzard has been Dumbledoring many of their characters in Overwatch recently. First Tracer is a Lesbian and then Symmetra is an autist. Now words confirmed that Soldier 76 is gay.
The act of ret-conning a character or historical figure as being homosexual (or some other sexuality) after the fact for the sake of being inclusive or feeing included with little regard for any evidence to the contrary.
An intense desire to die or to be killed as a means of escape from something worse than death, as seen in The Half-Blood Prince when Dumbledore screams "Kill me!" while drinking the poisoned water.
