look up any word, like tribbing:
Balls on the shoulder is a term for when one male party literally places his pubicle sack on a second male party's shoulder (either shoulder is acceptable). The act can be done either as a derogatory act intended to aggravate a homophobic individual, or can be done in the act of making love to create deep romantic affection.
Nate: "Hey Andrew, can I give you some Balls on the Shoulder action tonight?"
Andrew: "Yes, Nate, that would consummate our love for each other."
