Literally all you said“Marry me”
“Omg he looks so hot/sexy when he’s angry”
“(minor’s name) is hot”
“She/he can step on me”
“(name) is body goals” - when an idol’s body is really thin/stick thin
And anything that has to do with shipping idols romantically.
Also when they guilt trip the other fans in the same fandom that don’t contribute to streaming the song and voting for the group.
