There is a popular belief that links the origin of the practice to a form of punishment for adultery on women in medieval Japan. Indeed, bukkake is used in Japan to describe a type of dish where hot broth is poured over noodles, as in bukkake udon and bukkake soba. The word bukkake is often used in Japanese to describe pouring out a liquid with sufficient momentum to cause splashing or spilling. Kakeru in this context means to shower or pour. Butsu is a prefix derived from the verb 'buchi', which literally means 'to hit', but the usage of the prefix is a verb-intensifier.

The compound verb can be decomposed into a prefix and a verb: butsu (ぶつ) and kakeru (掛ける). In Japanese, the word bukkake has extensive non-sexual use, such as this food tent advertising bukkake udon noodles.īukkake is the noun form of the Japanese verb bukkakeru (ぶっ掛ける, to dash or sprinkle water), and means 'to dash', 'splash', or 'heavy splash'.
