The act of stalking a person on Facebook in order to like his or her status as soon as it is written. People most commonly likestalk their crushes, ex-boyfriend/girlfriends, or if they have neither, the "popular" kids at their school. Often done by refreshing the person's page every 5-10 seconds, clicking between the "Top News" and "Most Recent" feeds (which again essentially refreshes the page,) or (for very smart people) setting up Facebook so that it sends a message to the computer, TV, cell phone, house phone and iPod.
