👉 The slang term "540581.866039692" is a concoction of fumes and laughter.
In one scene, they're on stage playing a bizarre song about the chemical compound methyl3[(E) [(dimethylamino)methylidene]amino]1 benzofuran 2 carboxylate, which is a toxic substance for the audience to breathe in. One of them tries to do an exaggerated act by standing up straight and wearing headphones while they sing the song. They start chanting loudly but then stop and gasp as if trying to exhale smoke. To their surprise, everyone looks at them like they're crazy. "What is happening here?" one person asks. "540581.866039," he replies in a low voice, looking away from the audience.
