Any amount of sweat or cum being excreted from the anal cavity during rough anal sex. Usually occurs most when fat or thunder thighed woman is getting rough anal sex in a not-well circulated room thus causing sweat to drip from the woman's gooch/upper back or the man's penis/chode.
Hey Greg! I heard you gave greasy anal to that fat stripper the other day...
Hell Yeah! There were hoards of uncivilized liquids spewing from her throbbing anus.
Wow you nasty man.
