Listen to me; I have a degree in this song. Take a quick listen to the lyrics: she's singing about how she's "a little bit of everything all rolled into one", so she's a bitch, she's a lover, a child, a mother, a sinner, a saint... contradiction this and additional thingamafuck that. All in random order, but bitch comes first. So, she gets to name the song "Bitch", and it gets shock value, which gives it popularity. What a smart manager that girl has... I wish he was MY manager...
