Someone who donates their time and/or money to a cause or charity for the only reason of getting recognized and gaining personal popularity. A flaunthropist usually uses social media, etc. to "flaunt" their good deed(s). This type of person does not actually care about their cause / charity, but instead cares more about their perceived reputation as a selfless individual in the philanthropist community.
The only reason Becky puts on these charity events is because she's a flaunthropist with too much of her daddy's money and a thirst for partying and being popular on Instagram.
