While receiving a Blumpkin the person giving the Blumpkin vomits. This action is like a volcano exploding, sending vomit running down your shaft and balls like liquid hot magma.
Yo, my girl was giving me a Blumpkin last night when she gagged on my meat and turned that Blumpkin into a Blumpkin Volcano!

Sitting down on a toilet and taking a massive shit after eating a volcano crunch wrap, while at the same time, receiving a blow-job.
