Countach
I'd like to be driving my Land Cruiser one day, and come upon a Porsche or a 5 series BMW on the freeway. Maybe I would give the driver a nod, as if to say, "Hey dude, nice ride." And when he would give me the courtesy "My car kicks so much ass over your car, it's not even funny; and now I am feeling better about myself at your expense, thanks man" return nod, that's moment that I would push the button on my console labeled, Countach.
This is the part where my drivers seat drops down to the floor and the entire shell of the Land Cruiser pops off to reveal a Lamborghini Countach. (Please mentally disregard the Land Cruiser shell debris all over the freeway causing accidents or at the very least rubber necking)
As I glance over to my new little friend, I mouth the word, "Countach" to him. Because nothing says I so just worked you, like mouthing the word, Countach.
