Swass - an adjective describing the sensation of sweat from your ass lubricating your butt-crack to the extent that your underwear are soaked. This phenomenon is very common with tree-planting, vigorous summer exercise, or other notable swassy activities such as jogging. Swass often preludes chaffing of the ass-crack, but may also prevent said chaffing. Other variations of this term may be swits (sweaty tits) or swotch (sweaty croth). ass sweat treeplanting
