gerundickal or gerundical

I have long enjoyed how some words like picnic or panic get a "k" when you get to the gerund or present participle. That is, Édouard Manet and his friends were picnicking on the grass. You wouldn't want it to be picnicing because that would rhyme with the icing on a cake, not picnicking by a lake.

And then I came across havocked which I really liked. It's the past tense of havoc as in wreaking havoc or "The parade really havocked my trip through town but it was fun to watch."

This morning, I was reading the review by Robert Rubin of Shutdown: how Covid shook the world's economy, by Adam Tooze (Viking), in yesterday's New York times book review. Rubin says "The best we can hope for, [Tooze] argues, is what we in the United States got: disjointed 'subnational' action, crisis management by 'ad-hockery.' (Europe, Tooze writes, is even less capable.)." One does feel like they were havocked by the ad hoc over the past year and a half. But you can take pleasure in twisting words. Without the k, I guess ad-hockery would rhyme with grocery and not with mockery.
