Social Stroke 

A person's sudden tendency to purposely and deliberately do something awkward, cringy, or weird (but not harmful) in front of other people (usually strangers or people they don't know well), with the intent of being amused or entertained by their followed reactions.

John: *Gives a thumbs up to a random stranger he knows he had never seen before, then chuckles at their weirded-face reaction*
Jake (John's friend): "Again with your Social Strokes dude! If you don't care about your social image I do jeez! Just stop it!"
John: "Ahahahahahah! Sorry dude I just had to see his reaction I don't know what happened to me XD"
Jake: "It's called a Social Stroke... You always have them... And always when I'M WITH YOU!"

Socal Stroke 

Old School term used Hot Rodders and surfers from the Southern California area, circa the 1970's

Refers to someone who is always making excuses for not following through. Attempting to explain things away by glossing it over or leaving out the sordid details to make it look like it wasn't their fault. A person from Southern California who is full of BS or full of questionable excuses.

We drove all the way to Joe's place in L.A. yesterday to pick up the engine for the hot rod. He still doesn't have it finished. When we confronted him about it, he spun us a bull shit story about all the hold ups on the project. With him, it is the same old Socal Stroke!
