Mountain Dew Volcano (noun)
When you chug too much Mountain Dew and your bowels respond by turning into an erupting, neon-green, lava-spewing nightmare. Expect violent, molten diarrhea that explodes from your ass with all the subtlety of Vesuvius, coating the bowl in radioactive slime and making you question your life choices. Often accompanied by guttural moans, regrets about your sugar addiction, and the haunting knowledge that your bathroom will never smell normal again.
