To imply that someone is on your jockstrap area, which in a literal way means that this person is sucking your dick. It however is more like someone doing, saying, or acting out things
seen as fellating you or your
ego in a figurative way. Jocking is a variation of ass kissing in the sense the person is doing things that indicate some form of personal or
professional adoration, but jocking is typically sincere. It often leads to the mimicking of your behavior and emulating of your personality in the hopes of gaining your favor, attention, or affections.
