Facebook Chat blue balls
you think you're gonna chat with someone, but they're not there. You're left with blue balls because you thought you'd get some conversation, but now you're just sitting there like a fool

I thought I'd talk to my crush, but they were offline. Blue balls for life.
I was about to say hi, but they were gone. Blue balls, baby.
