A product so conveniently called "Subtle Butt". Labelled as a "disposable gas neutralizer".
Seriously?!!!!....I cannot stop laughing...
Here's the product description that comes along with it:
"Sometimes you just con’t control a gassy stomach...and what may happen as a result. But relax—the pressure’s off when you’re protected with these antimicrobial pads. Just stick to your underwear (even thongs) and go about your day. If you make a slip, don’t worry—the odor is neutralized by the activated carbon layer, and you’re spared the embarrassment. Great for travel, office or anywhere you’re in close quarters!"
Buy them here. (seriously?!!!)
