The All American Rejects: Gives You Hell - Song Meaning

What a song by a fantastic band, I think it's obviously a direct message to someone who broke his heart, probably because she thought he wasn't going to make it anywhere in life, and left him for someone with a promising future. Now, he hardly has to do anything besides rock out every once in a while lol, and all in all has a much easier and exciting life than the so called "successful" person with that promising future she probably left him for. The singer wants to rub it in that he's successful, while the heartbreaker lives a mediocre life instead of what she could have had with him, still working that 9-5. I say it's a direct message because of the line, "When you hear this song, and sing along, but never tell. Hope it gives you hell...etc." I personally picture the "heartbreaker" singing the song with a stressed look on her face with her friends, knowing that the song is directly about her, but everyone around her thinks its just a song.
