Why “hoboglyph” is a great word

HOBOGLYPH — [Noun] A utilitarian symbol, often chalked on a fencepost, curbstone, or railway abutment, left by a migratory worker to silently communicate local conditions to those who follow. From hobo (a migratory worker or vagrant) + glyph (a carved symbol or character). Unlike a "hieroglyph" (a formal element of a sacred, pictorial script) or "graffiti" (a broad category of unauthorized mark-making), the hoboglyph is a transient, functional code for survival. It is a cryptic sketch of a cat signaling a kind household, a set of crossed lines marking an unsafe place to sleep, or a swift arrow pointing toward a charitable kitchen—a fragile, ephemeral map of human need drawn on the margins of the world, the architecture of a transient trust.
