I liked the song. Rather than so many songs that focus on beign the "cool", popular kid, this song focuses on the fact that you have the right to be annoyed by people who try to make you act a way you don't want to. In the show, the girls are being pressured and hit on by boys who really don't understand personal space or the girls' right to say no. Onlookers comment on the guy's smooth moves. The girls, rather than buckling and staying in an uncomforatble situation, sing this song and refused to be pressured to act a certain way.
The song does have rhymes that, while not actually saying any bad words, refer to "bad words" (t*ts, *ss). These words are not said though.
