device commonly used to interrupt one's high school band practice the week prior to the big homecoming parade. may also be coupled with the use of profanity being aimed towards the band director (band director will usually become angered because the band is his or hers greatest accomplishment in life)
*long blast of one or multiple air horns* "eat camel cock,(insert band directors name)!!!"
