The feeling of disbelief and confusion when someone finds out that a person who they considered a good friend has blocked them on facebook. During the shock the blocked person trys to figure out why they were blocked, often resulting in a irrational feeling of being a creepy person or a stalker.
" Yo Bills in block shock. That girl Mary, the one he posts five times on her wall everyday, yeah she blocked him"
