A phenomena known as liking every single status of everyone on your friend's list. As soon as one posts a status, one likes that status, even if it is a depressing status or has nothing to do with the one liking the status. Also called Kerwinning, to Kerwin, or being Kerwinned.
Person 1: "Oh yeah, I just posted my new awesome facebook status!"

Person 2: "I'm going to like this even though it doesn't apply to me whatsoever!" *like*

Person 3: "AWW MAN! I just got Kerwinned!!"
