this occurs when someone follows another's twitter account religiously and the other person does not follow them, or evenknow he/she exists
"I freak out if I don't read every single one of @taylorswift13's tweets. I am completely obsessed."
"Does she follow you?"

"Ah, I see. Another depressing case of unretweeted love."
