What Does “Chk Chk Boom” Mean?

Chk Chk Boom uses the sound of a cocking gun as its central metaphor, constructing an image of Stray Kids as loaded weapons pointed at the music industry — ready to fire at will and impossible to ignore. The song is a maximalist power statement that revels in noise, energy, and confrontation, positioning the group's sound itself as a form of controlled detonation.
