Busting your pants
A particularly raunchy and violent passing of gas, typically brought on during the digestion period following a particularly high-fibrous or ethnic cuisine or meal. The act itself triggers a rippling effect in the affected person’s underpants. In rare cases, tearing can even occur, requiring a change of trousers.

Charlie: “Dude, I pity the producers and talent, you’ll be busting your pants all night long, better pack an extra pair of trousers!”
