On “Bitter Fuck,” Joji presents an introspective and critical evaluation of himself, and references a possible ex-lover who has made people see him as cynical and bitter.

In the visual for the EP, this song plays while action figures are caught on fire and melted. Many of the figures' faces—their most identifiable parts—are burnt first. This visual plays into themes related to the temporary and fragile nature of social identity: Joji’s identity has been damaged just like the toys' faces were.

On the clean version of the EP, the song is titled “Bitter.”
