Fubsy

I promised to explain the meaning of fubsy. Here it is.

fubsy \ adj [obs. E fubs (chubby person) ] (1780) : being chubby and somewhat squat.

Webster's Ninth New Collegiate Dictionary

I have used fubsy in the following sentence. About half of my readers have objected to this obscure yet descriptive word, but some change their mind. What's your vote?

"Wesley Peterson was the only Grover Springs resident to fully witness this vandalism. A fubsy thirteen-year-old with myopic brown eyes and mud-colored hair, Wes spotted the cyclone while walking home from his hideout on Wiggle Creek, where he played secret serenades for a herd of dairy cows."
