Giving someone a blowjob underwater upside down until they cum. You then proceed to blow it out your nose causing it to float to the top of the water like an underwater smokestack.

The act of balancing yourself on your shoulders and shitting blood and feces into the air, screaming VOLCANO!

This is what happens after you eat a large quantity of flamin' hot cheetos one night, the next morning you feel a rumble in your tummy. You go and sit down on the toilet and wait, soon it feels as if you are pooing lava! It is so fiery and hot, don't be surprised if it looks like blood with some cornmeal mixed in, it's just cheeto remnants. Ice cubes on your butt won't help but you'll think it might.
This morning I thought I was pooing blood! It hurt so bad! I finally realized it was just Volcano Butt from eating all those flamin' hots last night.
