Another one of the many different "nicknames" or "terms" for semen. When it is injected or "shot" into a female vagina, and combined with an egg, it could result in the creation of another human being. Could also be shot on the female's face and or breasts. Or in her mouth if she chooses to suck your dick.
Dipshit #1: Damn dude, I shot my super juice all over that bitch's face! It felt so good!
Dipshit #2: My super juice shot in my face when I was violently masturbating. It was a pain in the ass to clean up.
