look up any word, like bae:
 
1.
When A Professer of a college level class shows up fifteen+ minutes late. The students have the right to grab their books and walk out.

The Rule Of A Schmool
Professer must either A) Not Arrive or B) Arrive very late
We were siting in class until the professer walked in 20 minutes late. Then all of a sudden the students picked up their stuff and walked out justas he started speaking... it was at that point he knew the rule of schmool went into effect
