The title is "Sloppenheimer" now what is the plot of the film?

Clearly, it's about a wam producer who is literally 'da bomb'.

A story about the first person to get horny after getting messy

An attempt to get the most people messy simultaneously.

A scientist is trying to make the perfect gunge for dumping on someone. Then they all go out in the desert and build a gunge tank to test the gunge. They find out it's the best, most amazing gunge ever invented.

Then they fly the gunge to Japan and find a model to gunge. Then they gunge the model with the great gunge. Twice. The model enjoys it and the video sells well. The gunge starts selling on eBay for record profits and women everywhere are getting covered in this amazing gunge.

At the end, Sloppenheimer says to MessMaster, "When I came to you with that gunge recipe, we thought we might start a chain reaction that might get every girl in the world gunged." "What of it?" Messmaster asks. Sloppenheimer replies "I believe we did."
