Ok!
The people have spoken, and they want Hiro to hug the XXXX.
Hug it:

Hiro once again disappears from the frame, before exclaiming the following. Draw your own conclusions.

:
Komanechi!
What does that mean, you ask? Well. This one took some digging.
So apparently there was a Russian gymnast in the 1960s, named Comaneci.
Japan uses hard k’ and ‘ch’ sounds in place of c’ words in their alphabet. So ‘Ko-ma-ne-chi’ tracks with a literal translation of the characters in ‘Comaneci’.
Somehow or rather, I guess in the 1980s, this gymnasts poses inspired a early ‘meme’ of some vulgar dance moves, popularised by Beat Takeshi.
This is still prevalent in 2025 apparently, as I've been able to find references to it online.
Helpfully, we have this professional animation to explain the Comaneci for us:
So… uh… make your own mental picture of Hiro performing the Comaneci with this sex aid, I guess.
I'd once again, I’d like to remind everyone that this is a game about race cars.
