The wish a
person makes, usually the first
thing they think of, then blurt out, when they catch a leprechaun. Almost
always a terrible idea. Also applicable to other wish granters and devices, like genies, stars, and wishbones.
"I caught a leprechaun and wished I
never had to go to the dentist again, so now I have no teeth... what a wishfart."
"I wished I had a million bucks."
"You'
re rich!"
"No. I have a million male deer. Any idea where I can store them?"
"What a wishfart."
