Like Explode, but way more random, like, if you took, explode, and tied a hamster with a laser for a face and a pitchfork for legs to it, then you might have kursplode
Having so much fun in the company of friends you feel the need to explode. Most often occurring with many friends, and in this situation all of you are having immense amounts of fun, so much so, you simply cannot contain it and must spontaneously funsplode.
