Originated from Math teacher, Mr. Kamps, being recorded on camera. Since, it has been the root of several mashup-remixes, particularly "Gimme Four," "Scream, Aim, Four," and "Four Survior."
It is often shortened to, "FOUR."
Two short-lived metal bands have had this name, one of which was named after this incident.
Wil: How many minutes?
Steve: FOUR! (With Negative Four hand sign.)
