This song sounds like it’s about Jeremyy from “Quite Like You”
It narrates him being the life of the party, putting on a show and being loud and obnoxious.
The narrator is annoyed at Jeremy’s love life or how he’s cheating on Sherry.
He just cares about one of the people Jeremy is involved with. (Sherry or the other one?)
The narrator continues to be annoyed at drunk Jeremy and he leaves walking home cursing his situation.
