when a dudes' slacks are so tight they squeeze his twig and berries into a rhino beetle head shape to make them protrude like a ball-dick boner from said slacks; you know, grab a bowling ball with the correct grip (hand palm up, pointer and middle finger curved up and middle finger curved down, ring finger and pinky tucking into palm. pointer and middle finger would be balls shooting forward and up and thumb would be chub chub jutting forward and down.) now you see it, bro? ;)
