Why are some people's farts louder than others? Does the size of their butt have anything to do with it?

nope, amt, and speed of the gas

by not forcing it and maybe trying to hold it back.  if there is enough pressure for the fart to come out on its own it will, with no more sound than the sound of an air hose being turned on.  if you force it more air will come out than your anus can accomidate forcing it to expand and become a musical instrument.

I don't know. I must admit, I love fart jokes. I think its because it makes us all human, and even though I don't like to be immature, I really don't like fake or snobbery of any kind. \nWhen I get together with my sisters the topic of conversation always comes round to our latest fart stories. We just have a good laugh and feel better.

You are not farting enough. The gas gets trapped inside your fecal matter when you don't fart, and it makes it more bouyant. This can be very unhealthy. You should pass gas more often.

Because your poop don't stink?!

It depends on the permeation time of the smell (ie. dense gases spread faster in a closed environment than less condesed ones.)  Wind helps as well if it is an open environment.\n\nTo put it simply smell has too many variables to create a unified theory of odor permeation.\n\nBut I do know my farts seems to move fasters than other odors.

i would rather hear someone fart, it's so much funnier

because men are all alike. They don't care if they fart to each other's face. Yes, we do fart too.

As immature as it is, sometimes there is nothing funnier than a well timed fart. It has to be timed right though, like in Yoga or during Mass or something.

Just noisy when I am out in a public restroom trying to be quiet due to the large number of people in there...   Why this happens, I don't know.  I don't mind if it's loud when I am at home but DANG, when I'm out in public WHY does it have to be loud?  \n\n\nI fart a lot too.  Soy does that to me. And onions... and Taco Bell.\n\n\n:)

On a somewhat serious level:\n\nFlatulence is the presence of gas under some degree of pressure, in a confined space. The term is normally used of the presence of gas in the digestive tract of mammals, usually leaving a distinct odor. However, a balloon is flatulent as is a fizzy drink until the gas is released by opening the bottle containing it.[1] Though confused by the word's use as a euphemism for 'fart', flatulence is distinct from flatus, which is the release of such confined gas.[1] The distinction becomes very important in cases of bloat. In the animal digestive tract, the gas is produced by symbiotic bacteria and yeasts.\n\nDoes IBS or IBD keep you up at night?\nA population-based study by Mayo Clinic researchers on sleep uncovered an association between sleep and some gastrointestinal disorders. The authors found that people who had sleep disturbances were more likely to also have irritable bowel syndrome (IBS) than people who did not have sleep disturbances. It is unclear whether the IBS causes the sleep disturbances (or vice versa) or if they are both caused by another condition.\n\nOn a slightly humorous level:\nWe do not hold them in because we are not awake to think about it. Since it is a natural bodily function as gasses accumulate from functions within, it just does the natural thing. Hopefully, if you are sleeping with someone else, they are not awake, unless of course, you would like them to "enjoy" it.\n\nAnd, if you really want to laugh:\nhttp://www.heptune.com/farts.html?&referrer=http://www.jokeaday.com/\nThere is a subheading on sleep "gas passing" entitled:\nHOW LONG WOULD IT BE POSSIBLE TO NOT FART

It really means you are fun and nasty...\nBut basically yes... \nRead the composition here:\nNitrogen is the primary gas released. Methane and hydrogen, lesser components, are flammable, and so flatulence is susceptible to catching fire. Not all humans produce flatus that contains methane. For example, in one study of the feces of nine adults, only five of the samples contained bacteria capable of producing methane[5]. Similar results are found in samples of gas obtained from within the rectum. The gas released during a flatus event frequently has a foul odor which mainly results from low molecular weight fatty acids such as butyric acid (rancid butter smell) and reduced sulfur compounds such as hydrogen sulfide (rotten egg smell) and carbonyl sulfide that are the result of protein breakdown. The incidence of odoriferous compounds in flatus increases from herbivores, such as cattle, to omnivores to carnivorous species, such as cats. Flatulence odor can also occur when there is a number of bacteria and/or feces in the anus while being expelled. A small amount of solid or liquid fecal matter in fine particulate aerosol form may also be expelled, and included, along with flatulence.

Farts are primarily caused by bacteria that reside in your lower gut. They eat undigested foods that pass into the lower gut and as a byproduct of that, methane is produced. Beans, notorious for causing farts, contain large amounts of oligosaccharides, sugars that humans cannot digest, and bacteria digest these, causing gas.

if all the women in the world decided to fart everytime a man turned a looked at that spot, im sure there would be no more men in the world who would admire chicks with big natural butts.\n\ni always say, if a guy ever stuck his finger up my as$ id probably fart on purpose.

Its probably your breath blowing back in your face, and not the fart at all.

I can't figure that one out either. LOL! My boyfriend is a total fart-bag! I call him "Bazooka Butt". I will never understand it! I swear sometimes it's like one big fart-fest!

Neither will help! To light your farts, the gas coming out of your backside needs to be a lot and have the right balance between methane, oxygen.\nBut I wouldn't do that. I heard that a group of guys did that and burnt their butts. Their butt caught on fire.
