The Krakatoa 

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.

Gomez was overjoyed to see that the spurt from the Krakatoa was enough to drench the city of Pompeii.

The Krakatoa Eruption 

Performed during intense doggy-style action, right as you're about to cum, you shove your thumb in your partner's asshole, yell "IT'S ABOUT TO BLOW!" like you're warning a Pacific island village, and immediately spray them with a sudden eruption of chocolate syrup (or any other sticky substance you've cleverly hidden nearby). Bonus points if you throw flour afterward to simulate volcanic ash.

"Bro, she dumped me after I pulled The Krakatoa Eruption, but it was worth it. Her cat is still licking up the chocolate."
