Cabin Crotch
'Cabin Crotch' A condition caused by sitting in one place for long periods of time.

Symptoms: Warm crotch area accompanied by a musty, funky woft, due to poor air circulation and long periods of sitting down.

Sometimes an irritating itch within the crotch area would often indicate that its time to get out of your chair and have a little walk around, to perhaps 'vent' the area and relieve agitation caused by the stress of being seated..
