On an excavator's youtube work channel out of Derby Indiana, called Dirt Pefect, I just heard them say that vehicles repeatedly going through a low area in a filed had "wallered out a ditch."
In rural West Virginia I often heard this term used to mean the unintentional widening of a hole, like a bolt hole, and I may have heard it usd to meana the intentional wiening of a hole.
What I have not heard discussed here (?) is its use to mean the wearing away of threads on a bolt, which I also heard in West Virginia from auto mechanics.

  "Waller" comes from making a "wallow" - what pigs do in mud,
mostly to stay cool.
A waller not a well defined hole, so it is what happens to roads,
holes you drill that for some reason are more oval than round, or
holes / spots which over time have become out of spec if they ever
were one.
