Someone who drinks a lot of water and always keeps hydrated. As their name indicates, a water nigga's drink of choice is pure, clean, water, and they hold special disdain for carbonated drinks: those who drink large quantities of soda are dubbed "soda niggas" and shunned.
A water nigga can be identified by the water bottles they carry around.
Benefits of being a water nigga include improved concentration, greater stamina, and generally improved health.

- Yeah, he's a total water nigga. When he goes to pee he doesn't even need to flush because his piss is so clear from all the water he drinks.
