When you do a small race with someone in a car on a regular road and drive ahead of them but then the driver of the car behind you, knowing they have lost, decides to use the nearest turn as if signifying that they did not want to race with you in the first place and they lost because they wanted to turn when in reality they are just trying to piss you off instead of accepting defeat.
EXAMPLE #1

Porsche Driver: Yo, I raced this one guy in a riced Honda civic and when I clearly got ahead of him, he immediately used the nearest turn.

Friend: He really pulled the loser turn on you, he could not accept defeat.

EXAMPLE # 2

Ricer: Yo I raced this one BMW driver but they won so I immediately used the nearest turn to leave the road, you know, as if to give the message to the BMW driver that I was not really racing them. As if I am saying that I "lost" because I had to turn and the race was unfair because of that.

Friend: Dude, you really did pull the loser turn didn't you?
