That 'personal' moisture that seemingly comes from nowhere, and accumulates in or on your groin/genital/perineal/anal areas. Can be from: sitting too long; wearing too many layers of clothing; not washing often enough; warm temperatures; or even, as with women, they see something
hot, and get a little dewy down there; or with
men, if you
don'
t shake 'it' well enough.
After
four days of not showering, Jimmy had a mild accumulation of groinial
dew.
Sally was watching George Clooney on TV and noticed she had a
little groinial dew.
