I’m already on the record as being highly amused by the use of “set in stone” to imply permanence. I find “tectonic shift” and “glacial pace” equally hilarious, given that glaciers can move faster than plates. (Fast tectonic plates move at cm per year; fast glaciers can move at miles per year.)
In fact, geology terms provide a tsunami of really bad metaphors.
I think it’s time to fix that. Let’s suggest some geoscience terms that would make for good slang, if nothing else.
For example: Plinian, as in Pliny the Younger, Vesuvius, and Pompeii, to mean any kind of explosion.
“My dad’s going to go Plinian when he finds out what happened to the car.”
Or allochthonous, as in Highly Allochthonous, to refer to anything that’s really out of place.
“Did you see that guy in the tux riding up the Telegraph Trail?”
“Yeah. Never seen anything so allochthonous.”
And… I’m blanking. What about you?
