Status Cockblock 

When you post a witty status update that you know is gonna kill, and seconds later someone posts something about their dead (insert loved one/pet here) or about some earthquake in a third world country and totally steals your thunder.

I had a great status update and she commented about her stupid dead cat and totally status cockblocked me!

status cockblocker 

someone who the facebook poster does not know very well or like very much. By commenting, this annoying person will prevent the friends of the poster on commenting for fear of the situation becoming awkward between them and the blocker.

1. I wanted to comment on your statuses, but that status cockblocker michael feels the need to comment on every single one.
2. I do not know steve that well, and I can't comment on any of your statuses because that status cockblocker keeps beating me to it.
