I think it's just about all of the things she's done to change herself for all of these people, specifically guys. She's totally exposed herself and given up all her dignity to support or to get these people to like her but now she's saying she doesn't want to be their cheerleader no more, so they either take her or leave her. A great example is in the line where she says I played dumb when I knew better. It's a classic reference when people act stupid to get people to like them. But she's not going to do that anymore. She realized it just makes her a "dirt eater" or makes her no better but worse than what she was before.
