An inflammatory post, usually political or religious in nature, that you do not necessarily agree with but you are fishing for outrageous responses from your varied group of friends. Best done after a few drinks and after 11:30 pm. The enjoyment usually comes when you wake up to see the whale of a facebook comment mess you created when you've alienated and pissed off most of the people you know.
Choosing the proper lure can be challenging but pick something that even the most politically neutral will take offense to.
I was facebook fishing last night so I posted this: "So 49% of america voted for McCain and 51% voted for Black Bush. Sounds like the same old song and dance to me. Preventative attacks to stop people from dying by killing others in foreign lands. Yep. Great plan."
