Clear fluid that forms at the tip of the male organ after a prolonged erection. It can form in adolescents with or without stimulation or as a result of sleep or daydreaming; the purpose of such fluid is to provide lubrication during intercourse. Too much boyjuice can lead to a condition called Blue Balls for which the relief is usually masturbation.
Dude, after making out with Kayla, my boyjuice was running down my leg, for real.
