Thanks for the link, Jackie.

Back to Faldage's... His provided a term for an ironic device that we've certainly observed, but the term was new to me. I quote:

"mycterismus

Also sp. mycterismus, micterismus
subsannatio
fleering frumpe

A mock given with an accompanying gesture, such as a scornful countenance.


Example
In some smiling sort looking aside or by drawing the lip awry or shrinking up the nose, as he had said to one whose words he believed not, 'No doubt, sir, of that' -- Puttenham"

Might mycterismus be used with humorous intent of an ironic
observation?

Attempting to be less stochastic, assuming stochasticism may be considered here to be relative
