yup

The noise a small dog makes when inhaling large amounts of smoke.
It can also be the sound a dog makes trying to yip while its lungs are busting into flames.

"While the oven was preheating the dog began to yup repeatedly before bursting into flames like a Buddhist Monk"

Anne: "Did you here a yup?"
Travis: "Yeah, my neighbors got another dog so I'm taking care of it"
Dog: "yup!!! yup!!"
--Silence--
