Besides their game-day duties, the Aggie Yell leaders are the Masters of Ceremonies at the Aggie pep-rally-type event known as Midnight Yell Practice. This event is held the night before a football game, at midnight, at Kyle Field for home games or at a designated location in the opposing team's city for away games. During these events, the Aggie Yell Leaders tell stories about ways in which "Ol' Rock" the prototypical Aggie defeats the upcoming opponents' mascots and lead the crowds in yells, so that all attendees know what to do in the coming game. They lead an additional, smaller, Yell Practice on the Thursday night before all away games (even bowl games), called Arch Yell, which is held in front of the 12 arches at the entryway to the Corps of Cadets quad area.
