Imagine the worst, most foul thing you have ever smelled. An overpowering mix of rotting meat, old socks that havent been washed for weeks topped off with the pungent waft of an open sewer. . .Imagine being covered in the stuff as it is liberally sprayed from a water cannon. Then imagine not being able to get rid of the stench for at least three days, no matter how often you try to scrub yourself clean.
Beats my idea of Jalapeno hot sauce. Plus it would be a shame to waste the sauce.
