one of my friends explained to me that this song is somewhat about Madison Beer. How shes dated/been with most of the magcon boys and/or hooked up with them; explains the line "all of my friends seen her naked". Also, how she is know to rumors and thoughts about her; explains the title "bad reputation". She's been/dated with Taylor Caniff (thats why they hate each other and he hates Jack Gilinsky), Cameron Dallas, Jack Gilinsky, Carter Reynolds... < There is a whole list of who she has been rumored/dated, this is just naming a few of the boys.
