Tokyo Highway 

A adult version of a Hot Wheels or Matchbox car playset, making a series of intricately designed plastic track then pushing a small car along it with the car's goal to end up within the asshole of a unsuspecting person.

Intended for male or female victim.

So what are you going to do tonight?

I'm gonna grab my girl a do a little Tokyo Highway...
