When your dick's size becomes so
large that it reaches a critical
mass and begins to collapse in on the balls. The dick then retracts inside of the pelvis and forms a psuedo
vagina.
"Hey Bobby what's that glowing rod coming from your pants?!" "Oh thats just a dick implosion, an interstellar
mass larger than the
sun retreating back into itself so as to hide its
awesomeness from the world because the world cannot understand it yet."
