n.
an innocuous touch by someone just doing their job—a barber, yoga instructor, or friendly waitress—that you find more meaningful than you’d like to admit; a feeling of connection so stupefyingly simple it makes you wonder if aspiring novelists would be better off just offering people a hug.
In sports, incidental contact is a glancing touch that doesn’t rise to the level of a foul. A contact high is when you feel the effects of a drug vicariously.
