The short name for a chemical known as methyl mercaptan which is a naturally-occuring but toxic, smelly gas. Its chemical formula is CH4S which is very similar to methane (CH4). Both of these gases are found in farts and the mercaptan is responsible for the stench associated with flatulent activities.

An extremely stinky bathroom- one that smells like an overflowing septic tank is right underneath it. Meth labs generally have several stalls, each of which is equally noxious.

n. possible out come of performing Greek Fire. The lit penis can ignite methane gas in the gastrointestinal tract of the recipient causing an explosion, and thus creating penis shrapnel.

An underwater release of ones gases.

a animal that you squeeze its tits for milk.
a fat ass/somone who eats to much.
aparently o-zone layers are thinning because of its methane gas.

A person who eats meat virtually to the exclusion of vegetables. The people who call themselves this, who think they are saving the environment by "saving vegetables for those who will eat them", or bringing down the production costs of vegetables as meat-eaters, are not only flat-out wrong but immediately brand themselves as never having taken a post-secondary institutional science course (or remembered what they were taught in school about trophic energy levels).

As a refresher: In Ecology, you learn that it costs much more energy to create a tertiary consumer than it does to create a primary consumer, and that only 10% of the energy used on each trophic level actually gets passed to the next "higher" level on the food chain: the rest is lost in waste and reduced output of information and energy. In other words, it costs much more energy to create a Fox or a Hawk than it does to create a vegetarian Great Ape. Why? Because of the amount of food that it took (entirely dependent on plants as a keystone species), the energy, time and circumstance that it took each animal in that food chain in order to "be", while the Ape skips that whole process and eats directly from the fruits/vegetables of the earth. Thus, much less vegetables are consumed in the long run because it takes 85% of our food in America to feed livestock for slaughter that could instead be going around the world to feed hungry people 3 times over, while currently half the world is starving.

Calling this...

When you make a silent fart, sometimes, there will be a lingering smell. It will not go away quickly like a normal fart. It can smell like gas from the stove or it can smell like popcorn. Smells like it would be dangerous to light a match.

Is possible to occur after a loud, audible fart.
