When a certain gender can do something, but the other can't.
In The Odssey, double standards is when men are allowed to have affairs but women aren't..
When someone is allowed to get away with something others arent. when a particular standard is applied to a certain group but not another. this doesn't necessarily apply to gender but everything.
Politicians complaining about pet projects and pork spending as a problem but still pushing their own through because theirs is obviously more okay is a great example of double standards.
The smaller pay black soldiers receive was also a double standard
