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.

the 'fishy odor' is actually the definite term for those women who have discharges coming from their vagina that smells fishy... a characteristic of a discharge that is commonly caused by the bacteria 'GARDNERELLA VAGINALIS'.. GARDNERELLA is genus of anaerobic bacteria that would cause vaginitis or even late miscarriage in pregnant women.

Think of where it is coming from... \n\nThat HOLE isn't exactly the most beautiful place and (I don't know about you - but for me -  I don't particularly like to invision breathing the fumes that come out of that orifice)\n\nI think for many people it is similar - just hearing a fart makes them think - "Eww I am breathing the fumes that came out of someone elses butt!"  It's just gross.  \n\nSo yes - even though "smelly" ones are worse, the non-stinky variety are still YUCK because they are there.  We are forced to hear and then breath that air around you after KNOWING that you just farted.  :p

If there is a foul type odor, then there is some type of infection going on which needs to be treated by a doctor.

Thanks for that tidbit.  I had no idea. \n\nIn Spain, they have an expression, "to smell like an Englishman".\n\nI try to keep my wife happy, so I only bath once a week, to keep that *authentic* odour. </joke>

It means solid animal waste and it is used to represent anger or as a general common term for stuff. It is also used to replace curse words.

People can get used to their own smell and not realize that it's offensive to others.  So chances are that the "Something smells in here. Can you smell it too?" approach isn't going to work.  If they knew that they smelled they would (hopefull) do something about it.\n\nIn some cases, when someone doesn't just smell dank but is truly rancid I think it's a passive aggressive maneuver on their part. If the stench is that bad, others who are close to him/her must have mentioned it and the person is choosing to ignore their suggestion/request/plea and is therefore being passive aggressive.\n\nThe easiest way is to enlist a child to inform them of their problem. Kids are brutally honest and people seem to handle their criticism better than an adult's. One morning I hadn't brushed my teeth yet, and my wife's young cousin was sitting next to me on the couch, and I said something to her at close quarters and she scrunched up her face and said "Pew! Your breath stinks!" I laughed, apologized, and went to brush my teeth w/o any hurt feelings.  \n\nIf that isn't an option, the best way is to be direct, but not everyone can be that direct. Although if you can, I would suggest -not- being extremely apologetic, and don't mention that everyone has noticed it, and that it's been going on forever. Best case you say something as soon as possible because to me the real awkwardness comes when the person realizes s/he's been gagging people for weeks or months without realizing. Even if it's a lie you might say that you just noticed it, that way you avoid the "OMG how long has this been going on?" shame.\n\nSo if it were me I would not want, "You're a great person, and we respect you, and [...5 more minutes of buttering up...] but you have an odor problem, and we've all been suffering, and we've been trying to decide how to tell you for the last 6 months." Instead I'd rather get, "Hey, you probably don't realise it but you have a real odor thing going on and it would really help if you could try something different in your routine. I just thought you might want to know, no big deal."\n\nBe direct, be straight, be as concise as you can without sounding like a bastard. Most people try to add as much verbal padding as possible when they are trying to tell someone something that's bad news, embarrassing, etc. Just cut to the chase and get to the point, make the moment only as long as it needs to be.

Odors are also called smells. The term stench or pong is used to describe an unpleasant odor. The term fragrance or aroma is used primarily by the food and cosmetic industry to describe a pleasant odor.\n\nOdors that are mostly perceived as "pleasant":\n\nflowers, trees, some plants, baked goods, cologne, mint, fresh fruit \nOdors that are mostly perceived as "unpleasant":\n\nbad breath, foot odor, feces, flatulence, vomit, and rotting organic matter \nThe study of odors is a growing field, but is a complex and difficult one. The human olfactory system can detect many thousands of scents based on only very minute airborne concentrations of a chemical. The sense of smell of many animals is even better. Some fragrant flowers give off odor plumes that move downwind, and are detectable by bees more than a kilometer away.\n\nPheromones are odors that are deliberately used for communication. A female moth may release a pheromone that can entice a male moth from several kilometers. Honeybee queens constantly release pheromones that regulate the activity of the hive. Workers can release such odors to call other bees into an appropriate cavity when a swarm moves in, or to "sound" an alarm when the hive is threatened.

I think it's merely coincedental. A fishy smell from the vagina is usually a sign of infection.
