A sarcastic term used to ridicule those who don't know shit about cars. Similarly 710 cap and Muffler Bearings are used in this way.
"You need some blinker fluid for that?" Asked Tom.
Darryl, who knew nothing about cars and was knee deep in his truck trying to fix a broken radiator, replied "I don't know, I might."

A specialized transparent liquid used to lubricate the moving parts of a turn signal. Despite what other answers might tell you, it is absolutely not a joke.
"Man, these are the worst flashers I've ever seen. When was the last time you changed your blinker fluid? Oh, you didn't know that was a thing, well the repair's going to cost you pretty big." - My technician
