As defined on Urban Dictionary: The ridiculous notion that being of a different culture or race (especially white) means that you are not allowed to adopt things from other cultures. As defined on WikIpedia: When elements of a minority culture are used by members of the cultural majority, or vice versa; this is seen as wrongfully oppressing the minority culture or stripping it of its group identity and intellectual property rights. Simply put, cultural appropriation takes place when a part of a culture is adopted by another culture and no credit is given to the original culture that it belongs to. This becomes controversial when the cultural act in question is considered to be a brand new trend, instead of something that has been practiced for a long time by a group of people (most often a minority group).
NB: JAMHATIANADIAN refers to someone who is Jamaican, Haitian and Canadian.
