a noodle
When you and your band try to play music without the teacher telling you to. The teacher yells at you. Sometimes, the teacher picks on one kid and tells them to stop playing, even though the music is good.
@band: We noodled and got sent to the principal’s office.
@teacher: I told the drummer to stop playing and it was the worst thing ever.
@music: We noodled for so long, the music teacher died.
