Like blood brothers in a way, but closer. There are several ways that two can become nut buddies, of which all include mixing ânutâ (no homo though). For instance, if yâall are tappin the same girl at the same time, and your splooge mixes, you are then nut buddies (this is not to be confused with Eskimo brothers). Any instance where yâall niggas mix nut in a non-homo fashion makes you nut buddies. This usually means you have such an unbreakable (purely straight) relationship that yâall have mixed your potential offspring.
So Zach and I were tappin the same girl, and our cum mixed, we nut buddies now.
