Frôlés comes from the verb frôler, meaning "to brush against" or "to graze". It's a more evocative and less common word than simply "touched".
In the song, Tayc sings, "Où ton corps et le mien ont frôlés la Lune" (Where your body and mine brushed against the Moon). This poetic imagery suggests an intimate and almost ethereal connection, elevating a simple touch to something extraordinary and memorable. It's a beautiful way to describe a close encounter.
Tayc built “Toxic Boy” around a bilingual pun, playing the French word for “taxi” against the English “toxic” in the hook, and casting himself as the ex an old flame can't stop calling back. The verses list small, ordinary proof that she hasn't moved on — his number still saved, his messages never deleted — while the French lines call him harmful even as they admit she can't let go.
It reads less like a warning than a boast: Tayc knows exactly how bad he is for her, and the song's swagger comes from being wanted anyway. Switching between French verses and an English hook mirrors that back-and-forth, the language shifting the way the relationship keeps shifting between over and not-over.
