This is the bizarre moment a big-bummed Brazilian woman swings her huge hips to bump a complete stranger onto a display outside a store.

CCTV footage shows how the slender female pedestrian victim walks down the street alone, minding her own business, as the curvaceous woman approaches her in the opposite direction.

The curvy attacker, dressed in tiny shorts exposing her ample buttocks, then stops on the pavement and looks at the pedestrian as she swings her hips.

As the pedestrian walks by, the larger woman then skips sideways before her ample buttocks make contact with the victim, sending her flying into a storefront display.

The pedestrian is then seen falling onto the display, knocking over a fan and a drinking fountain as the woman continues walking along the pavement while looking back at her stunned victim.

The bizarre incident took place outside a ‘Ramsons’ store on Dr Moreira Street in the centre of the city of Manaus in the Brazilian state of Amazonas.

According to the time stamp on the CCTV footage, the incident took place on the morning of Friday, 15th October, with the clip swiftly going viral on Brazilian social media.

The women’s identities were not reported, and local media did not state whether the police are investigating the strange case.

It was not reported if the victim of the unprovoked ‘rear attack’ suffered any injuries.
