Australian breaker Rachael "Raygun" Gunn has announced her retirement from competition, citing a "really upsetting" backlash following her performance at the Paris Olympics.

Raygun, 37, became something of a global laughing stock after her unorthodox routine, which included kangaroo hops and imitating a sprinkler, failed to impress the judges at the Games.

Her moves were copied on late-night talk shows and her unfashionable green tracksuit was mercilessly parodied online.
