Whidbey refers to the largest island off the coast of the continental United States. It's located off of Washington in the Pacific Northwest. The whale part isn't what you think but has a common definition as Whidbey itself. It refers to the large woman that tend to inhabit the island. Everywhere you go, especially at night, there are going to be large women. They're known to be good at blowjobs but also a good laugh since after your decent looking, but drunk buddy sleeps with one-everyone except him in your cirlce of friends laugh about it for days and then continue to remind him here and there for a period of months.
Guy 1: OMG! can we find a bar that doesn't have whidbey whales or is somewhat exciting??

Guy 2: How about Anacortes?

Guy 3: Naw, that place is all antiqueish, full of old people and small-what about Coupeville?

Guy 2: I think we're fucked. Let's just go back and play beer pong til some navaho's look decent.

Get the whidbey whale mug.
Morbidly obese (i.e. overweight, fat, tubby, huge, and occasionally "big-boned") Women in the Oak Harbor/Island County of Whidbey Island, Washington. These creatures are of the pachyderm family, are mammals, and are the largest land animals alive today. Their habitat includes country bars, cheap nightclubs, and many of the fast food locations across the northwestern state of Washinton and southern Canada. W.I.W's are omnivores, spending 16 hours a day collecting junk food, beer, and large supply of Man-Beef. Their diet is at least 50% Hotdogs, supplemented with grease, burgers, fries, chips, candy, and small amounts of fruit juice, lean cuisine and diet coke. Scientists belive that because they only digest 40% of what they eat, they have to make up for their digestive system's lack of efficiency in volume. An adult W.I.W can consume 300–600 lb (140–270 kg) of food a day. 60% of that food leaves their body undigested, which is why they smell funny. They also give fantastic blowjobs.
