The Disappointed Black Guy meme, featuring the expressive face of Dieunerst Collin, perfectly encapsulates the universal experience of a sudden mood shift. The meme traditionally uses a two-panel format: the top image shows a state of pure joy or anticipation, while the bottom panel reveals a blank, deadpan expression of realization or disappointment. It first gained viral status as a reaction image used to describe situations where things take an unexpected turn for the worse. From sports upsets to daily inconveniences, this template remains a staple in internet culture for highlighting the thin line between excitement and total let-down.
