People, we are talking about farts here. No need to get so philosophical.
I'm on my phone so I'm gonna keep it short. We're talking about terms or definitions that can easily be defined by a dictionary, urban or wiki. Or simply explained by someone else. And if you want proof of experience, heck, I have chronic constipation, I'll just secure myself tightly under a blanket and rip a good one. How about that?
Or maybe do a "buffalo oven." It's a term my nephew came up yesterday because his farts were so toxic that everyone were holding their noses.
