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.
