What does it mean to exhibit something shamelessly or ostentatiously?

To exhibit something shamelessly or ostentatiously means to display it in a way that is meant to attract attention, often without regard for how others may perceive that display. The term that embodies this behavior most accurately is "flaunt," as it specifically refers to showing off something in an extravagant manner, making it clear that the intention is to impress others or draw admiration.

In contrast, the other terms have different meanings that do not align with this concept. "Forfeit" refers to losing or giving up something as a penalty, which is unrelated to the act of showing off. "Flop" denotes a failure or lack of success, which again does not convey the idea of exhibition or display. Lastly, "foil" typically means to prevent something from occurring or to contrast with another, which does not connect to the notion of ostentatious display either. Thus, "flaunt" stands out as the accurate choice for indicating shameless or ostentatious exhibition.
