Pre-Break Week is the week before any holiday or vacation for school. It is usually filled with many tests and homework assignments. For reasons unknown, teachers gang up on students and try to cram any last minute work they forgot to give their students in the prior weeks.
Joe: Yo man, my English teacher gave me 50 pages to read out of our book for Pre-Break Week. It's all due Thursday.
Bob: My History teacher is giving us a test Friday on all of the countries in the World. Man, I hate Pre-Break Week.
