A portmanteau of the words "seppuku" and "bukkake" meaning the act of ritual suicide by facial.

The seppukkake is performed after the practitioner has prepared his soul to leave the mortal coil through meditative rituals that vary from culture to culture, after which the practitioner typically submits to the seed. The seed is usually donated by honored guests and assistants, as this greatly increases the probability of seppukkake success through an abundance of volume, but the ritual is often performed alone and in secret by practitioners who are particularly dishonored. These latter practitioners have a much higher rate of failure and are regularly discovered in their homes' closets or bathrooms, much to their dismay, by parents, siblings, or spouses, and the practitioner then lives in further dishonor.

In historical context, it is believed that the legendary Musashi Hamtaro, after being bested in a duel in Japan some eight hundred years ago, committed ritual suicide by seppukkake to end his life's dishonor.
