Lucha VaVOOM wrestler Dirty Sanchez gave his image a dumpy update Thursday in Los Angeles ... hilariously appearing as a Donald Trump-like character at the company's event to fling some poop.

Sanchez walked to the ring at VaVOOM's Mexican Horror Story show wearing wearing a GIANT paper mache Donald Trump head over his trademark mask and calling himself "Donald Dump."

We're told Sanchez and El Chupacabra fought Los Pollos Locos and El Presidente ... but his team lost shortly after the Dump was smashed through the paper mache head.

Much to the surprise of nobody, Dirty Sanchez reached into the back of his pants after losing and began to fling fake poop at the other wrestlers and into the crowd -- something he's surprisingly known to do.

Wrestling, it's awesome.
