A charitable event.

Food (usually) chili is prepared and sold to make money for a charity. The Archduke of Austria Franz Ferdinand created the concept of the modern day Chili Slam in an effort to benefit the misplaced peoples of Yugoslavia. Sadly he was killed in Sarajevo on his way to host a major Chili Slam. A Chili Slam is usually hyped with such taglines as “Eat Chili for charity” and “Stuff a Bowl in your Hole”.
