When within the remaining few minutes of the last period of a school
day (specifically a highschool
class) a student deliberately rattles his or her chair around to
spark the process of the entire
class picking up their things and leaving.
Usually a few students are reponsible for being the catalyst of the movement and it normally occurs durring the time when the teacher is giving instructions for homework or summarizing other important details about the days lecture.
Variations of musicial chairs include the zipping up of binders, slamming of books, or putting papers away.
Toby wanted to get out of
class to smoke
weed as soon as possible so he contributed a rattling chair solo to the class inducing multiple students to join into musical chairs.
Jamal was in need of an excuse to conveniently "not hear" the teachers instructions for the homework, so he violently dashed his binder zipper back and forth for several seconds.
