Douche disclosure occurs when you have coordinated a vulnerability
disclosure with a vendor. The vendors agree on a patch release date. Then you, the researcher, begin talking about the vulnerability in the media weeks before the patch date. You get extra
douche points for naming the vulnerability, creating a logo, and publicizing this. For maximum douche points, you ensure that the name of the vulnerability points other researchers to the location of the bug in the underlying protocol, weeks before patch release.
Metzmacher
really stepped in it with his
douche disclosure of the Badlock vulnerability.
