says they're leaving facebook / posts about it on facebook... then never leaves.
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.
