When people (mostly locals that's been living in city or town for a long time) know their way around streets especially on stoplights, when you see the light red you find another route to your destination to make the trip faster.
Example 1:
Man- Whoa woman what are you trying to do pass that red light, you won't.
Woman- I'm just taking a roadinary route through this gas station. Its lot quicker than waitin at the light.
Man- No wonder why people say woman's drive crazy.
Woman- Stop your bitchin already
Example 2:
Man#1- Whats with all this traffic, mos def we're gonna be late with our dates. Ayo slow down. You're about to hit that car in front of us.
Man#2- Relax, stop squeezing your cheeks. I know my roadinary routine around this traffic
