Akata

Akata in Yoruba means foreigner
The meaning however increased during colonialism to stray cat or fox and was used to refer to white people ( white bitch)
The word was never created to insult fellow black people rather just to identify that there were not of the ethnicity and was only a slur for white people. however non-nigerians or non yorubas have misused it and changed the meaning with knowing the true meaning

Jamal is Akata ( Jamal is a foreigner) ( fellow black person)
John(white person) is Akata ( stray cat as Nigeria wasnt their homelands during colonialism)
