Any extended absence in the sexual career of a virile, heterosexual male in order to achieve peace of mind, recover from an STD, unplanned pregnancy, or emotional breakdown. An elective rest or hiatus, often lasting from two months to a year from having sex with multiple female partners. A Vaggatical is elective and does not count if erectile disfunction is involved, or if the guy simply cannot get laid.
I was sleeping with five different women during the same two month period when I realized they were all crazy bitches... I was at a party and four of them were there when I realized it was time to take a Vaggatical.
