Glouton literally translates to "glutton" in English, referring to someone who eats too much. It's an interesting and somewhat uncommon word to find in song lyrics, making it memorable.
In the context of the song, the artist uses it metaphorically. After his partner leaves, he says, "J'suis un glouton, j'ai tout mangé" (I'm a glutton, I ate everything). This suggests he consumed all the love, the memories, or perhaps even the pain of the relationship, leaving nothing behind. It's a vivid image that goes beyond its literal meaning.
Lomepal's "À Peu Près" is a really honest look at dealing with a breakup, even when you're trying to play it cool. He starts by admitting, "Elle m'a menti, pour m'protéger" [She lied to me, to protect me], and then, "J'suis un glouton, j'ai tout mangé" [I'm a glutton, I ate everything], which is a pretty vivid way to say he took it all in. Two months later, he's still struggling, feeling "plus qu'une moitié, j'suis plus que moi" [more than a half, I'm no longer myself].
He tries to convince himself he's okay, repeating, "J'suis à peu près sûr d'être à peu près quelqu'un de solide" [I'm almost sure I'm almost someone solid], calling the pain "rien qu'une petite entaille" [nothing but a small cut]. But then he talks to a photo of them, wondering what made her "quitter la fête" [leave the party]. And the most heartbreaking part? He still hopes she'll come back, even planning to "pas dépasser ma moitié du lit" [not go past my half of the bed] just in case, promising, "J'te demanderais même pas de raison, j'veux juste qu'on fasse comme si t'avais pas quitté la maison" [I wouldn't even ask you for a reason, I just want us to act like you never left home]. It's a really relatable picture of trying to be strong while still holding onto hope.
