A misspelling that teens commonly use when trying to sound edgy but are not ballsy enough to use "nigger". Common in American schools, Discord chats, and the few people that still use Kik as of 2017.
*Excerpt from a Discord chat, spelling corrected*
Person A- I don't like fat chicks.
Person B- Black people love em thick.
A- I'm not even black lol.
B- You act like a nibber.
