The speaker keeps laughing, but nothing about it sounds happy. The repeated "Laugh laugh laugh" works like a mask, or a reflex, something the speaker does to get through moments that actually hurt. Everything is called "funny": the system, the game, even the speaker's own honest thoughts. The more the word is repeated, the less believable it becomes.
Underneath the jokes there are hints of real damage. The speaker says they fall in love too easily and that someone "meant so much" to them, which suggests a loss or a betrayal. The line "I can't remember sound" feels numb and distant, as if the laughter has drowned out everything else. Then the ending cuts through the humor: "the handprints on my throat" points to violence or being silenced, and the laughter turns into choking.
The mood is bitter, tense and quietly desperate. The poem shows how someone can joke about pain because it feels safer than admitting it.
