Kuririn
There are a few things going on with Kuririn’s name, though Toriyama doesn’t really explain any of it (see below). First, kuri-kuri bouzu means a clean-shaven head, which certainly fits him. Second, 栗/kuri is Japanese for “chestnut”, which besides tying back into his “smooth head” image, is carried over into the name of his daughter (and in the anime, his early girlfriend). One of the title pages also shows Kuririn riding an air bike with the 栗/kuri kanji on the front. Finally, the “rin” on the end of his name may be a reference to the Shaolin monks (少林/Shourin in Japanese), a staple of martial arts films. “Shaolin” more or less translates to “little forest”, and the temple where Kuririn trained prior to become Kame-sennin’s pupil was called the Oorin Temple (多林寺/Oorin-ji), “big forest temple”, an obvious play on the name Shaolin. The Oorin uniform worn by Kuririn and his formal seniors at Oorin Temple are also clearly based on the Shaolin uniform.
Toriyama Explanation: “This is a name that I decided completely based on just the ambience from the character’s image. At that point, I didn’t think this was going to be a character that would continue to appear for a long time afterwards, so I used this half-baked naming.” [DBF]
