Aboriginal AFL player Adam Goode had a way of doing outrageous things on the football field such as doing a "war" dance and pretending to throw spears at the crowd when he kicked a goal. In one infamous incident, he singled out a 13 year old female spectator for yelling out "monkey" (an offensive term for Aboriginals) when his team ran out on to the field.
Needless to say, these actions didn't make him very popular with the spectators who booed him every time he touched the football. Ultimately this hostility from the crowds saw him retire from AFL football.
In the ensuing public discussions, Goode was never described as "racist" (though many had other nasty words to describe him). However, the acts of booing saw the crowds constantly labeled as "racist".
