trying to find old story, big fat inflation blow up

hi all. I've been searching for this story for a good few years now. it was the first one I ever read and I've always wanted to again.

In it, a women is inflated by a man in a grocery store, using a tube from a vat of food. He rolls her out of the store and rides her like a balloon to another planet. There she participates in a wrestling contest with other women. Small details I remember include the man referring to her as Blimpella and a version of the Oompa Loompa song the author made.

I found the story by google searching the term "big fat inflation blowup" and I think the title was something similar to that. I think it was part of the old AOL archive. Any help here is much appreciated!
