The term Nigger, was used in the mid 1900 as a demeaning term to describe a black person.
In the latest years the N-word "Nigger" is no longer seen as demeaning, and in black cultures often used as "brother"
The term nogger came up to get back to the original humiliation of the N-word, even amongst youth.
"Everything cool ma ho bro!"
"Look at those noggers! They can't even speak English properly!"
"One nogger down, one less to worry about".
