landwhale

An obese person.

There is nothing else to hit on here except fat girls so the landwhales just assume that since they have no problem getting dates that it's all right to be fat.

That's less lazy people getting Social Security, or taking jobs that us normal-sized people need. Eat yourself to death, landwhales!

An excessively large motor vehicle.

That jerk did such a bad job parking his landwhale that it's taking up four parking spaces!

"It's getting close to Timmy's bedtime, so we won't stay long. I suppose you heard us arrive. We'll be staying outside tonight in that land whale we drove up in."
