The chant is typically repeated in a rhythmic manner, creating an energetic atmosphere in the Allen Fieldhouse, the home arena for the KU men's basketball team. "Rock Chalk" has become a symbol of school spirit and pride, uniting students, alumni, and fans in their love for the university and its athletic achievements.
