Term commonly used in the Maritime provinces of Canada to describe the male genitals in a state of semi-arousal. Generally occurs as a pre-cursor to a full-out hard on, or after ejaculation, when you're hanging long and lazy.

When a guy is turned on, but not quite ready to grab a couch pillow to awkwardly conceal his arousal- an erection that is safe for public consumption- i.e. not pitching a tent, but beginning to feel aroused.
