When a video game becomes popularly hated due to its fandom as opposed to the game itself. Part of cringe culture. Often results in a hatewagon.
"Let's play Fortnite!"
"Eugh, why Fortnite? That game sucks. The community is filled with whining kids."
"Didn't you have the same reaction to Undertale? It was a good game but the community ruined it? Isn't most Fortnite hate just another Undertale effect?"
