Her poker Facebook, I'd already read it
She was pretending she’s not interested in Common, but her poker face was easy to see through: he’d already read it, like a Facebook page.
Note that on Facebook you can poke people, like how Common is “poking” her face. Common also references the popular website reddit with this play on words; “I’d already read it/reddit”.
