verb. To puff up, to swell.

The inflamed gout of polemical controversy..had gumfiated every mental joint and member of that zealous prop of the Relief Kirk.
The Ayrshire legatees, John GaltΒ (1820)

I hit my shin with a piece of wood last weekend — it immediately gumfiated. The painful gumfiation lasted for a few days, but now it’s back to normal.

This word is related to conflate but they don’t see each-other except at reunions and thanksgiving.

This word’s mouthfeel makes me think that this term can be best used to describe swellings that are particularly gross. To swell sounds logical and pretty straightforward, but to gumfiate sounds so much worse. I attribute that to the “guh” sound. You know, the sound of something gross and swollen.
