blinker douche
a driver of a vehicle in heavy traffic, that from an earlier, yet vain attempt at courtesy and using their turn signal, leave it engaged. then while abruptly changing lanes several times, cutting off other drivers, they realize it and disengage it.
Misty: Man I really hate people that don't turn off their turn signals and then drive like ass-hats.
Jeff: Yeah I hate blinker douches too.
Jeff: Yeah I hate blinker douches too.
