When the school announces there is a Hall Sweep on the intercom. You have to get to class before the bell rings, because the teachers will lock their doors and the security officers will come and get you. Then you get Saturday Work and have to clean thrash on Saturday. Hall Sweeps are announced during passing period and are usually called after fights, that usually ,but not always occur during lunch. Sometimes they are announced more than one passing period.
Bill: Look a fight!
John: Cool lets go see.
*watches fight for about 10 seconds*
*security runs to stop the fight*
Bill: Woah his nose was bleeding
(INTERCOM speaker announces -THIS IS A HALL SWEEP ,ALL STUDENTS OUT OF CLASS AFTER THE BELL WILL GET SATURDAY WORK!)
John: Oh crap, gotta get to class.
