Get the roadgasm mug.
The feeling of absolute joy you get from driving on a beautiful road, the view, the smell of petrol and your right foot pushing the gas pedal to the floor. You don´t have to drive a supercar or even drive fast. Just the feeling you get sitting behind the wheel and becoming one with the car, it´s like a meditation. But better. Much better.
Man, driving that Ferrari on the twisty road totally gave me a roadgasm.

I got a roadgasm on the way home, just me driving and a perfect scenery everywhere you look.
