Alcohol based disinfectant liquid used for cleaning the scrotum and guiche (collectively 'scrooche') on long hikes/ walks when soap and water are not available - to prevent unsanitary sweaty conditions in the groin region which lead to infection and consequent unpleasant itching.
Note: Burns.. alot. place liberal amounts on genitalia when cleaning.
Hiker 1 and 2 after entering tent at end of a days hike:
Hiker 1: 'ohhh man pass the scrooche cream, my groin is saturated'
Hiker 2: ' Wouldn't want anything growing down there'
