Well, you need to be more specific than just "Fortnite Kid." For example, do you mean an 8-year-old? Are they cringy? Do they like TikTok? Think of it that way.
I dont think you get it. Never said anything about fortnite kids that are cringy. But if you call somebody a fortnite kid then you are calling them good at fortnite because they play it a lot. And just because they like tiktok doesnt make them cringy.
