Not only is this one of the catchiest songs I have ever heard, but this unlike most popular songs, it also has a pretty deep meaning hidden in its lyrics as well. This is one of the main things that make me respect Billie's art even more. At such a young age, she addresses issues like no one else does. In this song, Billie is basically calling out all the people who claim to be the 'bad guys' or the 'bad boys'. Basically, there are two types of people. The first are people who are actually bad, and the second are those who pretend to be bad. Billie's song is giving the message that saying you're the bad guys does not make you one unless you act the part.
