When a person on Facebook feels it is necessary to post at least three times in a 24 hour period on something he/she will be doing or is doing in order to increase the amount of comments and "likes". Posting once that you are going to the show is insufficient.
FB First Post: "I am so bored at work right now but am sooo excited about the concert I am going to tonight!".
FB Second Post: "Sitting front row at the show! I will try my best to take some pics for you guys!".
FB Triple Post: "Tonight's show was the best ever. You guys missed out big time!".
