Used primarily in online classrooms; when the chatbox explodes with non-important topics such as the teacher's hair or a student's favorite aunt.

In physics class:

Dave: "Dude, my aunt is such a crazy cat person"
Mary: "Really? My uncle has a manic obsession with growing purple flowers"
Isaac: SOS guys
Teacher: Dave, Mary, and Isaac. What have I told you about talking about things not related to the subject material?
