Context: Kurogoma Katsuo 黒駒勝男 explains the perfect ratio of rice crackers to peanuts.
Note: kakipii 柿ピー is common mixture of two snacks, kaki no tane 柿の種, which is rice cracker shaped as a "persimmon seed," and peanuts.
kaki to piinattsu no wariai wa hichi tai san ni kimattoru yaroo gaaa!! 柿とピーナッツの割合は７：３に決まっとるやろーがァァ！！ The ratio of rice crackers to peanuts is [obviously] 7:3!!
kimattoru yarou - same as kimatte-iru darou 決まっているだろう.
yo no naka no koto wa subete kore, hichi tai san de picchiri umaku wakerareru yoo nattonja!! 世の中の事は全てコレ７：３でピッチリうまく分けられるよーなっとんじゃ！！ Everything in the world is this (like his hair), [created so that] [it] can be perfectly divided into seven to three!
wakerareru yoo ni nattonja - same as wakerareru you ni natte-iru-n-da 分けられるようになっているんだ.
hichi tai san ga uchuu banbutsu kongen no ougonhi ja, boke kora kasuu!! ７：３が宇宙万物根元の黄金比じゃボケコラカスぅ！！ Seven to three is the golden ratio of the origin of all creation in the universe, *expletives*!!
