A black person who is heavily invested into weeb culture. Usually extremely bland, and even more often addicted to sex and masturbation.
A typical Niggaboo will have anime as their only hobby, and attempt to force it into every conversation.
You know that guy, right? Such a niggaboo. He never shuts up about why Goku would win in a fight against every anime character. Who cares if he would win?
The act of using a goofy nickname for your boo or bae but if used as a trolling word, it can transform into your best friend's nickname. This word originates from a seventh grader calling his bae, niggaboo and then a few years later the guys sister told her best friend about it and its been used unironically ever since.
This is a slur used against black people who look very scary or live in a scary and trashy neighborhood. Like the trenches, the trailer parks, and even the crack house.
I passed by the trailer parks and saw a Niggaboo with sticks in its hair.
