I'm almost sure that "tongue tooth" means radula, a mouth's structure of the molluscs. Also, I think this technique is based on a snail that use acid secretion for feeding.--Spcmn (talk) 22:02, June 17, 2012 (UTC)

So... are you seriously saying we should rename this to "Radula Sticky Acid"?-- (talk) 22:38, June 17, 2012 (UTC)
Unless I'm mistaken, the kanji in radula and in this technique are in a different order. I don't doubt that this would have been the inspiration for the technique, but it seems not to be the actual name of the structure. Radula is 歯舌, and this technique is 舌歯.

@ Yes. A mollusc doesn't have a tongue. @Omnibender What if the kanji are out of order? Please, somebody check this.--Spcmn (talk) 23:01, June 17, 2012 (UTC)
The Japanese Wikipedia article for Naruto jutsu has it listed the same way we do. Omnibender - Talk - Contributions 23:09, June 17, 2012 (UTC)

Well, is worth for trivia.--Spcmn (talk) 23:31, June 17, 2012 (UTC)
