Daron is a French slang term for 'dad' or 'old man'. It's an informal and somewhat endearing way to refer to a father, often used in contemporary French.
In the context of the song, the artist is exploring the multifaceted nature of what it means to be a man, listing various roles and characteristics. Including "Un peu daron, un peu Christ" (A bit of a dad, a bit of Christ) highlights the contrast between the everyday, grounded role of a father and a more spiritual or idealized figure, making it an interesting and unique word choice that adds depth to the lyrics.
Jérémy Frerot's "Un Homme" [A Man] is a really thoughtful song where he's basically asking, "What even is a man?" He starts by describing himself with simple, human traits: "Un coeur, et deux poings" [A heart, and two fists], and how he lives and feels just like anyone else. He sings about crying, laughing, running, creating, and shining, admitting "Je sais, je ne sais pas" [I know, I don't know], showing that he's just as unsure and complex as the next person.
But then he brings in this external pressure, saying, "Toi tu veux un homme, toi tu veux un père" [You want a man, you want a father]. It feels like he's trying to fit into someone else's idea of what he should be, and it's making him feel lost: "Et plus je te suis, et plus je te perds" [And the more I follow you, the more I lose you]. He's trying to figure out what "Un homme au pire, au mieux, perdu" [A man at worst, at best, lost] means to someone else, and he's honest about his own confusion, repeating "Un homme c'est quoi je sais pas je sais plus" [What is a man? I don't know, I don't know anymore]. He lists so many contrasting qualities – "Un peu dur un peu fragile, Un peu libre un peu docile" [A little hard, a little fragile, A little free, a little docile] – showing that being a man isn't just one thing, but a mix of everything, and he's just trying to be himself, even if he's still figuring out what that means.
