The product of the penis as a result of a man excessively masturbating to the point where semen is no longer ejaculated, but rather replaced by a thinner fluid without sexual reproduction elements.
Dude, last night I was watching this porno and I couldn't stop masturbating until the point I was shooting junk water. Damn, my dick is sore today!
