A sad step below "Netflix and Chill", it's what you would do with some "bitch ass punk" you don't want to actually hang out with, let alone have sex with.
Guy: "Hey how about we go back to my place and we Netflix and Chill?"
Girl: "Ummm... How about we just "Spotify and Side Hug instead?"
Putting your chin on the left shoulder of someone you´re currently hugging is a clear indicator for the fact that you want to bang that person right then and there.
Yeah, she didn´t get the hints, so I gave her a left side hug and we went at it on the spot!
