By doing so you give a giant middle finger to societal norms and political correctness. Everyone will hear it and eventually the rancid fumes will reach their nostrils. What comes next is the reason why it's so courageous: the sheer disgust and revulsion shared by your peers generates a massive wave of shame that can crush even the most respected of normies. Usually most people slump down in their chair trying to get people to look away, or divert their eyes to the ground and quickly shuffle away from the scene of the crime. One must endure this. One must embrace it. Stand proud and smile. Grin! Laugh! Crack a shitty joke and brave the murmurs of displeasure that follow. The stench is your musk! Don't listen to your friends and family when they scold you for your actions. Let one rip at the workplace, the library, a fancy restaurant while with your significant other, funerals, crowded movie theaters and wherever you can think of. If you can't endure the shame of violating the few rules of common decency then you aren't a courageous person at all in the least. Be fearless. Fart as loud and as hard as your -blam!- will allow. Hold nothing back and release the storm.
