spider bark

To pass gas, to fart, gasses passing through the anus causing various fluttering or squealing noises

A highly elusive nocturnal specie of spider mainly from the Tennessee area (also known as the Tennessee barking Spider). While no live specimens have been caught in order to be studied, this is the only spider known to man with the capability to "bark". These spiders are attracted by the scent of bratwurst and sourcrout and also been known to emerge on taco tuesdays. While you may not see them, you will hear them and at times feel them scurrying through the couch cusions. They do use a foul odor as a defensive mechanism. Beware the silent Tennessee barking spider, it is a deadly sub-specie and should be avoided at all costs.

Dating back to Prehistoric times it is the only species of its kind to warn its prey by expelling air from its body, and releasing a nauseous odor. Extremely small it likes to hide in tight spaces like the pockets on jeans, and interacts, and is associated with most living beings.
