hyperiding
The act of utilising, excessively trading on or monetising current trends. Forms of hyperiding include promoting, reselling or creating goods of short-term demand predominantly apparel. Hyperiding individuals are so-called "hype riders", a closely related but more expressive synonym of the term "hype beast". Hyperiding is commonly used as an expression for exploitation of a trend, rather than the mere usage.
"Have you seen Monicas fake supreme shirt, she made herself?" - "Yeah, she's just hyperiding"
