Generally requires the wombing female to have recently ingested a chili filled bread bowl and cheap alcohol within weeks of frequent unprotected vaginal intercourse with unhygienic/unemployed sexual partners whose semen was left to decompose within her ample vagina.
The smell is so foul that it is presumed to incubate deep within the body, hence the root word 'womb'.
Although most frequently used as a noun (i.e. a womber), may also be used as a verb (i.e. "She has been wombing all night.")
Did someone just burn a pile of rotting skunk fetuses? No, the woman in the Bon Jovi t-shirt eating a taco just released a womber.
