You are driving a car.
You stop at a red light.
There is another driver also stopped on the opposite side of the intersection.
The light turns green.
QUICK!
Turn left in front of that other car.
Do not indicate.
You may be drinking.
We're late for soccer practice. Quick, take the Juba Challenge before that asshole comes our way.

It's 1980 and you want to go to the Flats from Superior Ave in Cleveland, headed east. At West 4th, the asshole starting across the intersection because the light has turned green thinks he can make it across before you dash left right in front of him to get to the flats. JUBA CHALLENGE! Hah! Showed you.
