Like blood brothers in a way, but closer. There are several ways that two can become nut buddies, of which all include mixing “nut” (no homo though). For instance, if y’all 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 y’all niggas mix nut in a non-homo fashion makes you nut buddies. This usually means you have such an unbreakable (purely straight) relationship that y’all have mixed your potential offspring.

Get the Nut Buddiesmug. A sex partner, usually a FWB, that you only allow to rail you from the back. Avoids eye contact, desire to kiss and limits the risk of intimacy and feelings. Keeps it all in the physical realm of pure pleasure only.
Anytime I get horny I just call my back buddy. He rails, nuts and leaves.
My back buddy really railed me food. My ass is still gaping.
