Typically used in schools. When a teacher or supervisor's not around and the student aren't doing what they're supposed to (i.e. Using their device, fighting, etc), a student that first notices a teacher is coming to their classroom yells to the class, "NINETY!". Which is a code word meaning a teacher is coming. The students can then quickly get back to what they're supposed to do.
Jack: Yo, Ms. Kira's coming back!
Sally: NINETY! HOT NINETY
*class scrambles back to do their work*
Ms. Kira: I'm back! Everyone doing what they're supposed to?
Class: Yes Ms. Kira
Ms. Kira: Good job!
Sally: NINETY! HOT NINETY
*class scrambles back to do their work*
Ms. Kira: I'm back! Everyone doing what they're supposed to?
Class: Yes Ms. Kira
Ms. Kira: Good job!
