The act of a man cockblocking another man with just their presence on on the girls friendlist on Facebook.com.
Sorry, I shouldn't have friended your girlfriend on FB. I didn't know she was that fickle. I'm so sorry for the facebook cockblock so please forgive me. I just wanted to be her to be my FB friend and nothing else. Just because I talk to her doesn't mean anything, but thats just from my point of view. I'm sorry please don't feel insecure about her feelings for you. I didn't mean for that to happen. You can keep that ho. I can't help it.

The inability to post anything potentially objectionable or politically incorrect to your facebook account out of fear that your boss or co-worker may see it and exact retribution or blackmail.
"Man, I would like to post this article about why marijuana should be decriminalized, but I can't because my boss could see it and then, there goes my promotion". "Dude, you're facebook cockblocked, for real".

Most often when a male encounters a female and gets the facebook add. The newly met female posts something flirty and is quickly met with a post right above by a girlfriend or the girlfriend's friend.

This is intended to let the male know that she read this new girl's post and does not approve of it.

NOTE: To prevent facebook cockblocks send private messages in the future.
Matt's facebook wall:

When all you want to do is chat with a girl on facebook chat, and chat just gets fucked up repeating posts and ruining your flirty mood leaving you with nothing.
"Yo bro I was chatting with Caitlyn last night, we was sharing secrets and all of a sudden facebook chat just got fucked up"

"Haha, man. You got facebook chat cockblocked"
