Other forms: flouting, flouted, flouts
To flout is to break a rule openly and without shame. Flout the rules, flout the ban, flouting the law.
The openness is essential, since flouting a rule means being seen to. It is confused constantly with flaunt, which means to show off, and the two mean quite different things.
