The bizarre sounds my stomach makes after I eat a lot of spicy food. Sometimes it sounds like there is a marching band in there.
Max: "What's with the noise, do you guys here anything?"
Sam: (Out of a sudden); "Uhm no, it's just my stomach, gastrophonics again."

Max: "Lmao, your stomach does know how to spin that shit!"

"OMG, I ATE SO MUCH, HOLD IT UP GUYS, I HAVE MY GASTROPHONICS COMING UP!"
