when you're jacking off in complete darkness, you finish the deed and the semen that shoots off illuminates in the dark, looking like a shooting star in the nightsky
After receiving road head, the person with the seamen in their mouth then spits it out the window onto the car next to yours. After this make a wish :)
when you're about to blow your load and you tell the chick you want to blow it on her face. just as you let loose, you aim your dick up and blow it straight over her head and onto her back, all while yelling, "make a wish bitch!"
"I gave her the best shooting star ever last night!"
"Did her wish come true?"
"Well if it was that I wouldn't blow my load on her face then it did."
