The result of ejaculating on a sexual partner with dark
skin. Named for the likeness of a clear
night sky (or planetarium) with the contrast of droplets of ejaculate on dark skin.

Hey, African
American girlfriend. Remember that
time I popped one out on your belly.
Tracy: Yes, Craig. The contrast of your ejaculate on my awesome dark skin reminded me of a planetarium.

Tracy: Sure ... I guess you could.
