If you're going to kick authority in the teeth, you might as well use two feet.

The line distills a defiant, anti-authoritarian ethos often associated with rock culture and Richards’s public persona. It suggests that if one chooses to challenge power—whether social norms, institutions, or gatekeepers—half-measures are self-defeating: the act should be decisive, committed, and unapologetic. The violent metaphor (“kick…in the teeth”) is rhetorical rather than literal, emphasizing intensity and resolve. Implicitly, it also critiques performative rebellion: if you are going to oppose authority, do it in a way that actually registers, rather than offering symbolic or timid dissent.
