1) A good song by the band Green Day
2) A combination of products that has been believed by many people to make someone's head explode when both combined.
While I was listening to Green Day, I saw this guy eat a handful of Pop Rocks followed instantly by a swig of Coca-Cola, then his head exploded like a watermelon.
