Buck the establishment

REBEL

Think of someone who defies rules or authority, often seen as a troublemaker in movies or history. The word starts with a letter that comes right before "C" in the alphabet.

"Buck the establishment" uses "buck" in the sense of resisting or defying authority, like a horse kicking against its rider. The phrase suggests going against the norm or challenging the system, which directly points to "rebel." It’s a straightforward definition with a slight nod to the idiomatic meaning of "buck" as opposition.
