Massachusetts Left 

While stopped at an intersection, A Massachusetts Left is the act of quickly taking a left as soon as the light turns green, in order to avoid having to wait for the line of cars heading your way to pass.

I was in a hurry, so I pulled a quick Massachusetts Left as soon as the light turned green.

Massachusetts left 

At an intersection unregulated by a traffic light, making a left turn by pulling halfway out into the road to block oncoming traffic while waiting for a gap in the other lane.

So common in Massachusetts that drivers will stop and wait for a left-turner, even when they have the right of way.

- You're pretty late today.

- Yeah, I got stopped by like four people making Massachusetts lefts.

Massachusetts Left Turn 

A Massachusetts Left Turn occurs when the driver of a vehicle, when stopped in impenetrable traffic or waiting for an inconvenient light, utilizes the empty oncoming lane of traffic to bypass the wait and make a left turn. This can range from a quick dodge around the car in front of them, to a full throttle blast down hundreds of feet of road. The longer the run between where the car crosses the center line of the road and the left turn, the greater the skill and daring of the driver.

We didn't move for 3 light cycles because those incompetent boobs were digging up the intersection again, so I had to pull a Massachusetts Left Turn and take side streets to avoid being late for work.
