Someone much more trendy than I needs to confirm if “brat summer” is truly over or not because its got so much more to give now that Billie Eilish is in the mix. The superstar has breathed new life into the phenomenon as she hops on Charli XCX’s cheeky-fun bop “Guess featuring Billie Eilish.”

The original, one of Brat and it’s the same but there’s three more so it’s not’s biggest bounces, is an unserious but honestly impressive escapade marked by a dialed-in electro bent and playful lyrical jests in the name of minding one’s business. The update remains just as light-minded, but becomes this monumental moment of virality with the addition of Eilish’s flirtatious nature.

Charli likes boys, but she knows I’d hit it
Charli, call me if you’re with it

That ear worm of a couplet is going to be ruminating in people’s heads for the rest of the summer. Just when you thought it was over too.
