NOT SURE IF MILF / OR HOT OLDER SISTER
A Not sure if troll post.
Not Sure If Troll is Fry from Futurama squinting suspiciously, used for the question every forum reader faces: is this person serious, or trolling? Captions follow "Not sure if troll, or just stupid." It's one of the main Futurama Fry formats and the meme for suspicion.
