A landwhale is a humanoid organism weighing in excess of 300lbs (although smaller specimens have been reported). They are often seen in the company of other landwhales and humans. Interbreeding between landwhales and humans, although once thought impossible, has been know to occur and produce viable offspring in isolated cases. In fact, it is rumored that humans can turn in to landwhales if they do not follow a healthy diet and excersize regularly; this statement has yet to be confirmed by science. Genus: Homo, Species: cetaceous.
The landwhale attempted to climb the stairs, but had to stop on the 5th step due to heavy breathing.

An extremely obese woman. More commonly known as a BIG BITCH. Often seen cruising buffet lines or getting smashed by guys who are hard up for some pussy. Much like a real whale, there is a lot of blubber and they secrete grease and oil. They often smell like stale fish although they rarely go in the water.
Hey man, did you see that land whale Mike was messin' with? I told him to watch out, now he went and fucked up and got that bitch pregnant. That's messed up.
