The Back of Your Mouth
Song Meaning

The lyrics suggest “The Back of Your Mouth” is about a sexual encounter built on flattery and lies, in which the narrator numbs himself and lets her words go right through him. The clearest evidence is the chorus, where the “dirty words” are “just passing through, not stopping by, not saying ‘Hi’” and the narrator concludes “you can’t kill a liar.”

The meaning

The song is about an encounter where the talk is empty and the narrator has decided not to take any of it in. The chorus states the method plainly: “In this exchange, I often touch myself / To go ahead and let those dirty words pass right through me.” The word “exchange” makes the whole thing sound like a transaction, and the words are treated as noise that arrives and leaves without being greeted (“Not stopping by / Not saying ‘Hi’”). One fan hears this as a casual fling whose words carry no weight because the two will not meet again 1. The lyrics support that reading in how they keep the narrator’s attention on his own body and off hers.

The verses explain why he refuses to listen. The praise is “sugar-coated,” and the narrator is “looking between your mouth and mine,” watching the distance between what is said and what is meant. The second verse repeats “These words are sugar-coated,” so the flattery is the thing he cannot swallow. The title’s “back of your mouth” fits this: it points past the pleasant surface of speech to the throat, where the lies come from and where things get thrown up. Verse 2 makes that literal with “You throw up everywhere.”

There is a competing reading in which the sugar-coating belongs to intoxication, with drugs making everyone’s compliments sweeter than they are 2. The lyrics do give the narrator a drink problem (“I’m all drinks / So I clean / I fall down”), and the blurred, stumbling syntax of the first verse sounds like someone not quite upright. But the two readings fit together. Being drunk explains why he is slumped, numb and detached, while the sugar-coated words are still hers, and the target of the song’s contempt is the lying, not the drinking.

The ending shows that he is not above the ugliness. The narrator admits to cruelty (“Grab soft I still cut out her tongue”) and the scars, scabs and ashes are what the encounter leaves behind. Cutting out a tongue is the obvious answer to a liar, and the chorus undercuts it at once: “you can’t kill a liar.” The bridge and outro repeat that phrase until it stops sounding like a taunt and starts sounding like a defeat. Wounding the person who lies does not stop the lying.

Taken together, the song is a portrait of two people using each other and both knowing it. The narrator’s defense is to feel nothing, and the cost is a ruined encounter that ends in scars and a refrain he cannot make true. The song never resolves, and the repetition at the end is how it shows that.
