I doubt it has enough context lenght for that, even if we suspect someone was watching nudes on car's display via Grok.
What is probable - is that somewhere beneath it had a data entry of soccer and nudity together, maybe even as an exact exchange between users (imagine horny boomer commenting under a random facebook post). I suppose that it got triggered by words "soccer" and "mom" appearing together in kid's speech, as this combination means middle-aged woman with kids, and that is also a less popular tag pointing at MILFs.
