The sexual act of ejaculating into your partner's navel and then proceeding to slap the area on or around the belly (preferably the lower abdomen a.k.a. FUPA) creating a ripple effect that forces the ejaculate to spray from the navel. Many pride themselves on their Krakatoa giving ability. The ensuing explosion is often compared to a volcanic eruption, hence the slang Krakatoa.
