Assplosion is a collection of 5,000 explosive birds. When you get a bird you will earn an ASSplosion try. That means you can try to blow the ass off of a random bird.
But calm down, you will only have a 50% success ratio, which means only 2,500 birds will explode (and their respective artworks will change automatically).
