The act of body slamming during live shows. It's not moshing as it is basically a glorified shoving match. Only 10 or 15 kids will partake while others have a fear of being demolished. So named because of the type of 'moshing' during broken ritual shows, a band originating from Downingtown.
Dude 1: 'Hey man, wanna mosh?'
Dude 2: 'I prefer Downingtown Slamming'
