when your asscrack/grundel area is so sweaty it basically becomes a boggy swamp. very humid and producing unbelievable discomfort, this condition is generally worse among the fat and lardy. however, in sub-tropical climate locales, i.e. southern louisiana or mississippi, swampass can strike anyone, at anytime. the only relief is to either strip naked and head for a fire hydrant or go home and peel your loins off and drape a cold, wet towel over your nether-regions.
