Example:
"In this section, we investigate the band structures of plasmonic ribbons with four types of boundary conditions, i.e. zigzag, bearded zigzag, armchair, and bearded armchair"
(from "The existence of topological edge states in honeycomb plasmonic lattices")
I now have this mental image of the author sat there for three hours trying to come up with a name, and then just exploding with "fuckit! I don't care what it's called! It doesn't matter. I was sat in an armchair when I thought of it, so armchair it is! If they can have strange quarks, I can have armchairs"

You misspelled "mice".
I can't imagine that, do you have a link to explain it or is it a joke?

Imagine stacking marbles. They'll naturally fall into a hexagonal pattern as the most likely way of naturally stacking.
More relevant, though, might be the shapes you get when packing spheres: https://en.m.wikipedia.org/wiki/Rhombic_dodecahedral_honeyco...
