A partially visible penis extruding from the waistline of a mans pants. Just like the female equivalent, this can be accidental or on purpose. The most popular sighting of dick cleavage usually involves somebody wearing their pants too low, to the point where you can see the beginning of the person in questions shaft. The less noticed sighting usually occurs when a male achieves an erection and flips it up into his waistband, causing the head of his penis to become dick cleavage.

1. "So on the bus yesterday, when Josh reached up to grab the loop to hold on, his shirt pulled up and everyone saw his dick cleavage."
