creepin' the light

When someone is waiting for a red light to change, and they keep inching forward a little at a time until the light changes and they can take off.

"Dude, quit creepin' the light. It will change soon enough!"
"I had to pee so bad that I was creepin' the light in order to get here faster."

Tail Light

A person thats not bright.

James: "Check out my Honda Civic (D-series)"
