Rule 0

It usually works better if you plug it in. This rule applies to all electronic devices and most other situations by analogy.

Day 0

When an attention seeking emo/wemo tries to go so many days without cutting themself, then they fail. (They go back to day 0)

Whenever something bad happens, no matter how pointless, say 'Day 0' to mock the attention seekers, but also as a sign of respect to people who cut because of mental illnesses.

Luke: Damn I just stubbed my toe!
All: DAY 0!
Kristen: I forgot my homework!
All: Day 0!
Sam: I'm on Day 41! I hate that number!
All: Day 0
