Lyric discussion by A7XBulletForMyValentineLover 

If you've watched the video as many times as I have you would know that it's about a guy who hooks up with my girl and she seems to think that she's dating him but later in the video she walks in to see that he was hooking up with another girl and pours "gas" (actually water) on the bed that he and the other girl was in and on him and the girl and acts like she's going to set them on fire. So it's definitely about someone who's heart has been broken
