Singer Tay Jardine explained the song's meaning to Kerrang! October 18, 2014: "Manners is about a relationship that has gone sour. They're lyrics are about how hard you fall for that relationship without seeing the same effort in return."
"It's something I had gone through a couple of years ago. Manners became almost like revenge. It was me saying, 'This is how I felt, but I wasn't able to say it at the time, when I was actually in that moment.'"
The third verse of "Mmm Mmm Mmm Mmm" by Crash Test Dummies ("they shook and lurched all over the church floor...") was inspired by girl whose parents would speak in tongues at their Pentecostal service.
