Describing an FPS player whose skills and strategies are so advanced that they consistently top scoreboards and outmaneuver opponents with apparent ease, much to the chagrin of their rivals
To unexpectedly excel in a competitive FPS setting, especially when outplaying a player who is typically superior. The term combines the idea of a "boost" in performance with the sly cunning of a "goose."
"He was playing so casuallyall night, but in the final match, he totally goostered and took everyone by surprise."
Originating from a bizarre incident where a player managed to defeat an entire team single-handedly while a pet goose honked in the background during a live stream. "Gooster" has since become synonymous with a gamer who performs so outstandingly well that it seems they must have their own cheering squad, even if it's just a goose.
"Remember that gooster moment? I swear, every time he plays, it's like his goose is right therewith him, cheering him on."
