A stench that's described as “mephitic”

Is so bad as to be paralytic.

Which is why my dog's name

Is a mark of his shame.

Old Meph sports an odor armpit-ic.

There are smells that are classed as “mephitical”

For example: reviews harshly critical.

But a fetor far worse

Can aggrieve and accurse:

It's the hot air that's labelled “political.”

Based on the suggestion: "mephitic"
