An awesome wrestling move. It involves going for a double leg takedown, but instead of putting your head at their beltline you put it under them and then lift up. With them on your shoulders and holding their legs, then you let the legs go forcing them to fall to the ground, similar to a dump trucks bucket.
Mike was acting tough and wanted to wrestle me so i gave him a nice Dave Yoder Dumptruck .
Keeping with the spirit of the "Three River City", the Pittsburgh Dumptruck occurs when three participants, or "defacateurs" proceed to defecate or "poo" on the chest or upper torso of another participant, willing or non. Said occurance need not occur in or within the vicinity of the City of Pittsburgh.
Dude, that bitch loves a good Pittsburgh Dumptruck, you guys want to drink draft beer all night and shit on her?
