As the name implies, an ICB is an unexpected boner that pops up during class. This can easily happen when sleeping or daydreaming in class. The ICB is most annoying when it happens right before the class ends.
I fell asleep during lecture today and woke up with an ICB, so I performed a belt tuck to hide it when class ended.

An “ICB” or “Ice Cold Beer” is a term to describe a chilled alcoholic beverage. The term doesn’t technically refer to beer specifically but describes the wide variety of cold alcoholic beverages.

ICBS!! No way she wants a guy that only lasts 5 minutes. She’s only saying that to get more OnlyFans Subs.
