Song

When the two girls get sad and fake-drunk on fake-wine to cheer themselves up, there's an awful, hysterical pop song that they're listening to, with the lyrics, "I pledge allegiance to the party, C-O-L-A and Bacardi." I cannot find any existence of this song online anywhere, except one site which is a transcript of the movie. Was it written and performed just for this movie? That would be even weirder.
