Definition:
Nocturnal Shopping is The act of spending money while wide awake at night—usually during episodes of insomnia—when you should be sleeping, journaling, or praying. Often accompanied by deep regret and Amazon, Walmart, or Macy's email confirmations. (The behavior of browsing or purchasing items online in the late-night or early-morning hours instead of resting, commonly justified as harmless but often leads to unexpected credit card charges and impulsive buys.)

Whenever a male is sexually aroused during the night and wants to masturbate but is too lazy or scared that he will wake his parents up when he moves to get tissues. He then masturbates with the intention of not nutting but ends up losing control and overestimating his choad causing him to nut all over himself. This putts him in a much worse situation than before by forcing him to get up and clean it and also risk being caught by his parents with the task of explaining why he has nut all over himself. Basically, a literal fucking nightmare come true.
