The phase in someone's life or online presence where they shed irony and lean into wholesome, earnest, slightly cringe sincerity — and somehow it becomes their whole identity. Your acoustic arc is when you stop trying to be cool and start posting about sunsets, learning guitar, and genuinely meaning it. It can be endearing or alarming depending on how far they go. Frequently observed after a breakup, quarter-life crisis, or someone discovering folk music at age 22.
