Noun. An extremely voluminous fart which often does not have the usual tell-tale "farting noise;" but rather a large "whooshing" sound due to the unbelievable amount of gas being released. Also noteworthy for its characteristic ability to produce significant, hot breezes that can move small objects/clothing, be felt escaping the bottom of a pant leg, or can even be felt by others. Often rated in terms of typical weights in pounds for very large human babies.
