Vriller literally means "to drill" or "to spin like a drill". However, in modern French slang, it's often used to mean "to go crazy," "to lose it," or "to spiral out of control."
In the context of the song, the artist sings "Réapprendre à vriller" (Relearn to go crazy/spiral). This suggests a desire to reclaim a wilder, less controlled part of herself, perhaps as a way to cope with heartbreak or to rediscover a lost sense of self after a difficult relationship. It's an intriguing and less common usage that adds depth to the lyrics.
French pop artist Adèle Castillon brings a catchy post-breakup track about drowning out emotional chaos by turning up the volume. She describes feeling overwhelmed after giving everything to a dramatic relationship that fell apart with lies (Tu me mens et je m'éloigne [You lie to me and I move away]). Instead of staying stuck in her sadness, she turns to her music for therapy, admitting that she only talks to her piano (J'parle qu'à mon piano [I only talk to my piano]) while listening back to her own song demos.
Adèle blends everyday English slang with French idioms to show her messy headspace. She pairs the modern anxiety of having her heart in FOMO (fear of missing out) with watching her ex cry in slow mo', all while her memories are torn to shreds (Souvenirs en lambeaux). When she sings about cranking up the sound system to remember her ex's flaws à la folie (madly / to distraction), she flips a classic French romance phrase (from the flower-petal game un peu, beaucoup, passionnément, à la folie) into an obsession with remembering why they broke up in the first place.
