The white creamy liquid also known as semen that comes out of one's meat when he has finished bopping it. Bopjuice is characterized by a fast, furious spout, rather than a splooge. Often hits the meat-bopper in the eyes or gets on his clothes.
Dude I was boppin my meat and by accident the bopjuice squirted on my glasses.
