a way for white folks to say the n-word without getting their eye-teeth slapped in. Comes from Dave Chappelle's skit "The Black White Supremacist," in which Clayton Biggsby's overdone backwoods Southern accent turns the short "i" sound to something more along the lines of an "ay" sound. variations include: Nayger, negar, nahger etc.
"I hate neagers!" - Clayton Biggsby, a fictional KKK member (played by Dave Chappelle) who was born blind and raised by white supremacists, thus hating black people without ever realising that he himself is one.
