when little white kids talk online and instead of saying nigga they type ni99a...it's because they're too scared of typing the word out because they're afraid of getting their asses kicked by some actual black guys

Ni99a is the kind of word you use in games like RoBlOx or MiNeCrAfT to swear without getting banned
