Top Definition
Rice crust is the tiny speck of sperm that gets left inside the urethra just at the tip of your penis after you ejaculate. Over time, it hardens up and blocks the inside of the urethra. As a result, when you go to pee the next morning, you have a pee-splosion as the pressures rips the solidified piece of ejaculate out of your penis leading to a sharp pain.
Yo man, I spiderman-ed the bitch last night! Although, I paid for it the next day with a rice crust in my penis. Karma is a bitch, I say!
