Attack - The first note of a piece.
Check - A said piece without rolls or hard rhythms.
Stock - Normal, as written; to go back after changing an exercise: "alright, play the exercise stock. Also, expected: "geeze, best tenors, so stock!"
Apparently - Used to mock anybody that gives directions. Usually not an upperclassmen or director. "Oh, apparently we are doing fundamentals today. Kevin knows!"
Spike and Spock - The high and low respectively, usually 6 or 8 in. drums on a set of sextets.
Ham it up - To walk around out of tempo to no specific drill set. Usually arms are waved and silent taunting takes place.
Those are some my drumline uses.
