Ah, but wait a minute... It all depends on the context of how it's being used in a sentence.
DW can actually mean a number of things. Actually, something like nearly 100 of them. For example - dry weight, dead weight, Doctor Who, don't worry, dishwasher, double window, domestic water, doo wop, deadly weapon, damage waiver, dim wit, drywall, dedicated wife and Darryl Waltrip.
So when someone says DW, DW loves the new DW you'll know exactly what they mean.
