Crapfishing
Deliberately posting inaccurate information online for the purpose of humour, with the aim of getting lots of comments and reactions from people who a) don't get the joke, or b)do get the joke but feel compelled to comment in a way that lets other people who got the joke know that they too got the joke and are thus smart, funny, sexy, handsome etc...
Oh look, Dave's just posted how Darth Vader is his favourite Star Trek Character because he's such a positive role model for disabled people. Looks like he's Crapfishing again.
