While waiting at a traffic signal for the light to change from red to green, you notice that the left turn arrow changes green without the forward light changing green. Just by seeing the light change you step on the gas alittle bit and then realize that your lane is still stopped. Causing the car to flinch. Typically implies that you are alert or that you are in a rush to go somewhere. Senario may be applied vice versa.
(While second in line waiting at a traffic signal in the forward lane)
Driver: I really hope the light changes soon.
Passenger: Yeah me too.
~Left turn lane changes green, but forward light remains red~
~ Car first in line on forward lane begins to go as if the forward light was green, realizes it is still red and stops; causing the vehicle to flinch moving forward a few inches~
Driver: Whoa! Did you see that guy ahead of us!?
Passenger: Yeah! He just did a Signal Flinch!
Driver: He must be in a rush to get out of here.
Driver: I really hope the light changes soon.
Passenger: Yeah me too.

Borussia Dortmund's home ground with one of the best atmospheres you can find in Europe. Worth a visit by a neutral fan as they also play exciting games.

🤙🏾🤙🏾 When you’re chill no matter what the outcome is you do the Flip hand signal. Derives from cowanbunga surfer attitude. Use both hands only one if it’s not that chill.

A set of lights on a vehicle that, when activated by the driver, flash in pairs in the direction of a turn.
Dumbass 1: is that where we're supposed to turn?"
Dumbass 2: "Yes! Put your turn signal on!"
Dumbass 1: "why would I ever do that???"
Dumbass 2: " so people behind us know that we're going to be making a turn!!!'

used in various fields, more predominantly in computer or electronics fields, to indicate inbound data that is being detected but the source of the data cannot be determined.

When you purposely get a red light and/or take a red light so you stay in the same area of the car so you can check out a hot girl in a car.

What is signal stalking?

Refers to da random bu**s**t blinker-operations dat you brainlessly display to hapless fellow motorists after your having partaken of one or more "tall and strong" bartender-blended drinks in Margaritaville.
Sending mixed signals during turns or lane-changes may not actually indicate dat your car is low on blinker-fluid; instead, it may show dat YOU YOURSELF are "over-filled" with some OTHER type of "fluid! :P
