To me it sounds like she's outside her ex's house and has all of these negative things to say (the bag of hammers) but she won't go inside because she still has her manners. Previously, they maybe had a discussion which ended with her partner leaving (on the interstate bus).
And from "Shake, shake..." to "...ice cream" it seems like her anger toward her ex pleases them.
