A drumline tradition during which new bass drummers must stand on their heads while inside their harnesses being held up by their drums. After this they are officially part of the marching band. (Filming is optional but highly recommended.)
Shannon: Hey Jack get over here!
Jack: *starts walking*
Shannon: PUT ON YOUR BASS DRUM! NOW!
Jack: *scared* ok... *puts on drum*
Shannon: *pushes Jack onto the ground head first and makes him do a bass drum roll*
*Pat walks over and starts filming*
Jack: Are you filming yet?
Pat: No not yet
*This continues for two minutes*
