pontiac game changer

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.

Pontiac Tom 

A person who LOVES pontiacs. This type of person's car is black. This type of person always talks about doing stuff to his / her car, but never really seems "to get around to it" nor is able to afford it. Enjoys rubbernecking at accidents, and pretending his car performs well and is naturally better than all other cars (even though it isn't). Also, enjoys spontaneously buying stereo systems for his / her car without consulting anyone with knowledge on it.

Man. Would you look at that Pontiac Tom? What a queer.
