Exactly; squarely; precisely. Saying something is "on the nuts" is akin to saying it's accurate and "on the mark." The phrase arises out of the experience of getting hit in the nuts, which, when hit exactly or squarely on the nuts, is much more significant than otherwise. Thus, you say something is "on the nuts" when it is exact and precise.

An engulfing ejaculation so powerful that it will not only blow your dickhead off, but it will stretch your dickhole so far that everything dribbles out and you can make hand signs with the excess skin.
Becky: "Ew, why yo dickdribbling?"
Randy: "Cause I just had the biggest nut nut of my life."
