when you post a comment to someone's status update, and after refreshing you realize someone else made an almost identical comment at the same time.

People who use the comments section of any social networking site to engage in discussion with others who have commented on a particular photo, status update or other newsworthy item which is totally unrelated to the original post and particularly annoying to everyone else that receives updates of all comments.
Mark: Hey all, did you see the sunset today? It was awesome! Check out this photo.
Tina: Oh man, no, I was stuck in the office.
Geanny: YES! I love California sunsets.
Bill: Hey Geanny, haven't seen you in a while.
Geanny: Oh hey Bill, nice to hear from you, how are you?
Bill: I'm great, the kids are great, my wife recovered from her knee surgery just fine.
Geanny: Oh wonderful to hear, Bill, we should meet up for lunch sometime.
Bill: Great idea Geanny, how does tomorrow sound?
Geanny: How about at Starbucks?
Bill: You mean the one over in Irvine?
Geanny: No Aliso.
Tina: Guys, can you take this conversation offline, I'm in Dallas so I don't need to hear about your coffee date!
Geanny: Oh sorry, I didn't realize that everyone was getting these messages.
Bill's WIFE: Bill who the hell is Geanny?
Bill: Uh oh, I'm in trouble now!
Mark: Haha, that's what you get for being a Comment Jacker!

One who comments on a facebook status with a random word, or stupid joke that no one understands or everyone hates, therefore causing other people the sudden urge not to comment on it. Usually this person is not liked by anyone on facebook, and in most cases real life.
