Why this word is great
JUVENOIA — [Noun] The fear or hostility directed by an older generation toward a younger one, or toward youth culture in general. Coined by American sociologist David Finkelhor in 2010, from a blend of juvenile (from Latin iuvenis, "young") + paranoia (from Greek παράνοια, "madness"), it is the institutionalized suspicion of the next wave of humanity. Unlike "ephebiphobia" (which fixates on adolescents) or "generation gap" (which describes mere divergence), juvenoia is a reflexive dread of cultural evolution itself. It is the tutting disapproval at slang that sounds like static, the moral panic over new music that feels like a physical assault, the conviction that the youth are not merely different but somehow worse—a quiet terror that the future will erase you before you are ready to go.
