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!"

Usually takes place during a game of Tease and Denial when a man strokes his erect penis in front of a woman with whom he is playing the game with. This is meant to show respect and worship towards the woman playing the dominant role of the game. The man is generally not allowed to ejaculate during this time.

Sexual position similar to missionary, but the guy uses the headboard to hold his weight up, which makes it look a lot like he's doing the butterfly stroke in bed. Popularized by leaked footage of the movie Breaking Dawn. Almost guaranteed to make a girl faint if she likes sparkling vampires.
I didn't think my boyfriend knew anything about the Twilight Saga, but then he tried the butterfly stroke on me in bed. He can't deny it anymore.
