An ironic reference to ABC college football's "Pontiac Game Changing Performance". A fundamental shift in the status quo; a significant beat change that affects the perception of or outcome of an event. Also serves as a tongue and cheek commentary on our culture's reliance on corporate sponsorship for any and every little thing.
I didn't think Rebecca was into me, but then at 2 am last night she texted me to come over and smoke pot. It was, to say the least, a real pontiac game changer.
