The act of a male grabbing his shaft and thrusting mightily until he expels bopjuice and his shaft then goes limp.
"Dude, I came back to the dorm room early last night and I caught you boppin your meat. Next time you do that, lock the door man."

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.
