The douchebag index (DBI) is a statistic that yields the number of days since a person last bathed. It is found by multiplying the number of visible tattoos (VT) by the number of missing teeth (MT).

DBI = VT X MT
This dude's douchebag index is 27, meaning that he hasn't bathed in about four weeks. He has nine gross tattoos and three missing teeth.

Jeff: Dude I'm buying real estate here, look at all the hot swimsuit models and the tanned guys with abs
Tim: That place has a high DBI (Douchebag Index)
Jeff: What does that mean?
Tim: You're better off living in an Igloo next to an active volcano
Jeff: But then what if my Igloo springs a leak?
Tim: You'll have some lava in the living room big deal. At least you'll have a low DBI.
