Facebook Chat blue balls 

when you look at your contacts on Facebook Chat, notice someone's online, click their name, then it tells you they're offline.
thus, you are left with "blue balls" because you thought you could get some Chat on and you're left wanting a conversation

Damn, thought he was online... Now I got Facebook Chat blue balls.

Chat Blue Balls 

The angst and sexual urge you feel when chatting with someone online and you really just want to see them in person instead. Like actual blue balls, this can be temporarily relieved by jerking off, but is only truly resolved by visiting the person of desire.

Don't type so dirty like that, it's giving me chat blue balls again.
