Douche Bag Squared
Someone who is so much of a douche bag that one cannot just call him/her a "d-bag" or "douche" or just plain ole "douche bag." So you have to multiply douche bag by douche bag to truly define the individual as a super huge douche bag or just aptly put...d-bag squared. I.E.(d-bag^2)
John Frey is a douche bag squared(d-bag^2)
