Boston Left 

A driving technique for turning left onto a busy road with no stoplight. You use the middle left-turn lane (also known as the suicide lane) as a buffer before merging into the lane you're actually supposed to drive in.

Friend: How are we supposed to turn onto this road? There's always a car in each lane.
You: Guess we have to make a Boston Left.
