What the fuck is dark humour??? A dark humour joke is a joke which directly harms a society , a colour , or a race. It may directly or indirectly trigger racial discrimination. It is never supposed to be cracked in public. You don't want to get beaten up after all. Or worse could happen. Dark humour jokes are cracked to harm directly or indirectly the person in front of you or a third person. A dark humoured joke for example : What is the difference between a black guy and a pizza ?
