Flout v. flaunt

To flout means to infringe, break, ignore or  disobey a law - often in an outrageous, egregious or explicit manner

To flaunt means to show off, display, often in an ostentatious and disagreeable way.

Thus, you flout the rules (break).

You flaunt your wealth (show it off in a manner calculated to engender envy in others).
