look up any word, like blumpkin:
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.
"I was at Joe's party the other day, we danced, ate good food...in the end we all funsploded."

"Did you see me earlier? I was hanging with my friends and I totally funsploded!"
