Gamos is French slang for a 'luxury car' or 'fancy car'. It's a modern, informal term that you wouldn't find in a standard dictionary, making it interesting and unique to contemporary French music.
In the song, the singer watches his partner's "gamos s'Ă©loigner" (luxury car drive away), emphasizing the dramatic departure and the high-stakes nature of their relationship. It adds a touch of modern realism and a specific cultural context to the lyrics.
"Love Therapy" is about the aftermath of infidelity. The narrator admits he cheated on his partner with a "side chick," and she finds out and starts packing to leave. He begs her to stay, promising he's done with the other woman and ready to do anything to fix things.
As she walks out the door, he watches her go and keeps asking himself, "Putain, qu'est-ce que j'ai fais?" ("What have I done?"). The song repeats his apologies and regret, showing a relationship falling apart from his own mistakes, with him powerless to stop it.
By the end, he's still pleading for forgiveness, admitting he's the one at fault and that he can't get her back.
