When you've been holding in a fart for too long / but growing up everyone told you that ladies don't fart
A Annoying Facebook Girl meme.
Annoying Facebook Girl is a photo of a young woman with a cheerful, oblivious smile, used to mock the oversharing habits people show on social media. Captions describe vague status updates fishing for questions, endless selfies, relationship drama posted for everyone and questions a quick search would answer. It's the meme for attention-seeking posts on the timeline.
