If a rv has a door on the left side of it, itnis a symbol to the others in the campground your lbtq+ friendly and open for "meeting up". Similar to a pineapple on the door of a home of swingers.
You see that tranny walking across the campground last night? Popped right into that left door over there since a Trailer Left Door is the universal symbol for that stuff.
Similar to a Pittsburgh left except that multiple vehicle make the attempt. Vehicles will generally keep turning left until the opposing traffic forcibly asserts the right of way in a manner similar to a game of "chicken." Named for a practice common in Shanghai, China and other crowded cities in Asia.
"Wow, look at all those cars and trucks attempting a Shanghai left! I can't believe there aren't more accidents here. The highway department should install green arrows and turning lanes."
If Your A Guy With A Left Erring Your Actually Gay.
Dude, You Have A Left Erring. You Must Be Gay.
