A term used to refer to the sub-section of "Gamer Bro" culture that has a very bad habit of using slurs and racist remarks while playing videogames. Alternatively refers to racist people who also play videogames.
This discerns from a slur form and the slang form of the word "nigger". If pronounced with a hard 'R', its considered racist. If its pronounced with an 'a', phonetically spelled 'nigga', the term is not meant as racist rather as a sort of nickname, like buddy or ace.
