Flashboarding is a term that is used to describe the action of a person flaunting their wealth in a vulgar manner. However, there are several other synonyms that can be used in place of this word. These may include showing off, boasting, ostentatious display, parading, exhibitionism, and flamboyance. All these words are used to describe someone who is excessively showing off their wealth or achievements, and they all share the same negative connotation. A person who indulges in such behavior is often perceived as arrogant, vain, and pretentious. It is important to note that showing off is not considered an admirable trait, and it is crucial to remain humble and grounded in all situations.
