The author tried the angle of making up cuss words, which in by itself is trying to be creative if they try a variety, but they only made up one phrase. However that being said, the author made a horrible, HUGE error with making said cuss words overly used. You could even hear it in the narrators voice that they were getting irritated. Every time it was used I would stop paying attention to the story because, I would be thinking how many times is the author gonna try say it in the same paragraph.
