I really really do. "You're going to let your ass say its piece" needs to be a riot grrrl band.
There are certain situations where it may be impossible to get out of a crowd, and the fart must be passed. Say, for example, you're in the crowd at a sold out show, or you're waiting in the security line at O'Hare Airport. If you can't hold it, you're going to let your ass say its piece and deal with the aftermath. You can try to mitigate the smell — for example, if you carry scented lotion in your purse, take it out right after you fart and start nonchalantly applying some to your hands. Nothing to see here. Just a lady passing gas and moisturizing — or you can deny that the smell came from you. Whatever you do, if you plan on seeing any of the people around you again, do not raise your arms triumphantly over your head and proudly proclaim your stewardship of the fetid air now passing into your fellow humans' nasal cavities. This is widely viewed as rude behavior.
