Fukasmoe

Anyone know what a "Fukasmoe" is?

Shae and I went for a long walk this evening around the neighborhood.  Shae starts singing "Fukasmoe!  Fukasmoe!  Fukasmoe!" over and over again.

So I whisper (in case someone hears me saying the F-bomb to my kid), "Shae?  What is a .... fukasmoe?"

Shae says, "Fukasmoe... lives on the farm.  It eats.  A FUK....A....SMOE"

I said, "Oh.  Right.  A fukasmoe."

No idea.  Antelope?  Really, no idea.  I agreed and tried distraction: "Oh!  Look!  A kitty!"...as I pointed at NOTHING...

"Home, home on the raaaaaange!  Where the deer and the fukasmoe plaaaaay..."
