Polished Man 

a campaign that encourages people to actively take a stand painting one fingernail (usually blue but it can be any other color) to raise awareness and to end violence against women and children.

usually the ones that paint their fingernail are men (since around 95% of all victims of violence, experience it at the hands of a male perpetrator and approximately 4 in 5 family and domestic violence offenders are male).
you can learn more about this campaign on the polished man campaign site (where you can also donate).
