Purple nurpled brother in law?

I’ve grown up nipple twisting my old brother, and boyfriends while playing around. Including my now husband whom I’ve dated since 17.

Just like giving someone an Indian burn or a slap on the back of the neck. Not meaning anything by it perversely.

My recent brother in law was messing with me and keeping my book out of my reach, so I purpled nurpled him. I’m recently married to his brother although I’ve been in a close relationship with the family for nearly a decade. Is this weird? Should I not do that? We’re in our 20’s and he didn’t reAct strangely.

Possibly overthinking lol
