Flaunt and Flout :




To flaunt is to show off: you flaunt your new necklace by wearing it to work.


“Flout” has a more negative connotation; it means to treat with contempt some rule or standard.


The cliché is “to flout convention.”


Flaunting may be in bad taste because it’s ostentatious, but it is not a violation of standards.
