Listening to the lyrics of the song is totally different from watching the video. Most of the video is empowering for women. Lil' Mama picks up Avril Lavigne in her shiny pink car. They both appear to be promoting sisterhood and solidarity. The video does not seem to match the lyrics of the song at all.
The music alone is another matter entirely. When a love triangle is set up in pop media there always seems to be a "cat fight". On one end of the corner there is one woman who says she's better and can do more for "the man". On the other end of the ring there is a different woman that says she can do better for "the man". Instead of one woman saying it we've got two women saying it! The video appears to be promoting sisterhood, but in reality, it is used to disguise what the song is really about. The focus of this song is about how a woman wants a man to dump his girlfriend for her.
The potential lover might need some assistance in deciding which woman to pick. There are several examples laid out in the lyrics as to reasons why the other woman needs to be kicked to the curb. Mind you, they are not his reasons for dumping her -- they are another woman's reasons:
1. She is stupid.
So when's it gonna sink in
She's so stupid
What the hell were you thinking?!
2. She is less of a person.
She's like so whatever
You could do so much better
That is exactly what we women need. We need to convince men that other women are stupid and less of a person. Why in pop media are there so many women that do their men’s dirty work? If the guy is really thinking about two different women (or more) at once, why would the characters Avril Lavigne and Lil’ Mama portray be any different than the other women he’s interested in?
