L.T.L.
A Left Turn Loser is a driver who thinks they're king of the road just because they can do a left turn in a lane that doesn't belong to them. They block traffic like it's their job.
I swear that guy did a left turn in the middle of the highway like he was doing a magic trick.
She merged into the left lane and then did a left turn like she owned the road.
That L. T. L. blocked me for five minutes just to turn left into a gas station.
