FELLAS, I GOT THE RESOLUTION OF THAT "THAT JUTSU- QUESTION".
First:
Thanks for the links, they are backing up my resolution. As most of you are confused by the talking of J-Man and Gamatora (the toad), i'll explain it to you. To your idea: I think that the "Menacing Ball" could just be a possible result in succession of learning "that" sealing jutsu.
Back to my point.

again.
Jiraya was referring to Naruto's Rasenshuriken when he said "That Jutsu". As we know all the backgrounds, Naruto learned RS before, beat Kakuzu with that and after that battle Tsunade found out that the RS-Jutsu is destroying his body. As we also know that J-Man talked with Tsunade about that, he just told Naruto not to use "That *RASEN SHURIKEN* Jutsu".
And now look here,
THE PROOF!

Gamatora, the toad, remembered Jiraya what happened before when he was opening Naruto's seal by a little. This seal is declared as "the 4t's jutsu", the
Shishou Fuuin, the 4-Element-Seal. Remember about the "Ying-Yang" talking in the last chapters? Minato only sealed the YING, the good part of kyuubis' chakra, with a double Shishou Fuuin in Naruto - he sealed the chakra twice because to heighten the effect of the seal, but he also let some cracks left that the chakra can flow so that Naruto could use some of the kyuubis' chakra. The double-Shishou Fuuin is called the
Hakke no Fuuin Shiki, the Eight-Tigrams-Seal (Logical: 4x2 = 8, so the name Eight Tigrams).
The YANG chakra, the bad part of kyuubi's chakra, was also sealed with on a SCROLL. As we know we need both Parts, the YING and the YANG, to complete something, in this case gaining control over the WHOLE chakra of the kyuubi's.
SO LEARNING "THAT JUTSU" IS REALLY THE HAKKE NO FUUIN SHIKI. SO NARUTO NEEDS TO LEARN "THAT JUTSU", THE HAKKE NO FUUIN SHIKI, TO GET CONTROL OF THAT YINGYANG-SHIT, THE KYUUBIS CHAKRA.

Well ok, it's not as that clear as it has been shown, but look at the seal on that scroll, count the Triangles (=7) and than count the Circle (=1), so we have 8. So it's named "Eight Tigrams". On the picture above, you can also count the circle and than the things arround it, it counts 8 in the end. I already told you that this seal, the Eight Tigrams, is on Naruto!
Oh and by the way, the Hakke no Fuuin Shiki was developed by the Uzumaki..and guess what..Kushina was Uzumaki, Naruto is an Uzumaki...
Hmmm...is it clear now?
Reps to me or die.
