Nigga Balls HD comes from a video of a balding white man with a beard very exaggeratingly shouting out someone on Instagram named "big black nigga balls hd", followed by other Instagram accounts he shouts out in the same clip.
The resulting odor on a male’s nut sack from recent intercourse with a female who previously douched prior to sex. The subsequent “extra fresh” smell on the man’s junk is reminiscent of vinegar emitting from an opened jar of pickles.
Bro, before work I went balls deep at Stacy’s and I just got a whiff of a ripe case of pickle balls. I hope no one smells it.
