A speaker climbs a mountain wanting only one thing: to be left alone, away from noisy teenagers and online arguments. But the escape doesn't quite work. Even surrounded by rocks, trees and early flowers, the mind keeps thinking in hashtags, the shorthand of social media. The speaker offers a list of "suggested" tags for the day, and they swing from jokey to bleak: death, bodies feeding flowers, a self-made god that will die too.
The turn comes near the end, with the line about having "two copies of every friend." It suggests that online versions of people feel doubled and unreliable, and the speaker can't tell which one is real. The sore limbs bring a loneliness that can't be posted.
The mood is wry but sad. The speaker doesn't love or understand the natural world, only accepts it, and that quiet acceptance contrasts with the final cheerful tag, "great day outdoors," which now sounds hollow and ironic.
