New term for a bodily function

From a Thomas the Tank Engine book by the Rev. W. Awdry:

Gordon never stopped, but he never failed to say "poop poop" to Thomas. And, Thomas always said, "peep peep" in return.

This morning as Larien was going pee pee in the potty she passed some gas. It sounded like the way I read the "poop poop" in the Thomas story. So, I said to Larien, "You just made a sound like Gordon."

Larien laughed, then she said, "I made a Gordon sound."

So, that's what I'm going to call passing gas from now on. Many of you will understand why that is doubly funny. Larien certainly finds it very funny.
