A whole aisle in a drug store devoted exclusively to vagina maintenance. Usually trafficked by the fairer sex during the worst week of the month (for both sexes !). Men are seen more and more these days cruising the vag aisle to help their lady friends in order to secure later entrance to the other type of Vag Aisle.
Dude, why are you shopping in the Vag Aisle ? Well, because I am whipped and I want access to the Vag next week.
