These people are either real fans or
fake fans.
A real fan usually has been a fan for a long time, and likes other bands similar to them such as P!ATD, Green Day, My Chemical Romance, etc. and likes songs other than songs from the
Save Rock and Roll album.
A
fake fan usually is a fan of mainstream/pop music and discovered Fall Out Boy from the radio, when it played "My Songs Know What You Did In The Dark (Light Em' Up). That is basically the only song they know. They label the band as emo, even though they are clearly not.
