Crazy Party

In the Korean comments

The comments reveal that the clip is using a meme obscure enough to become part of the joke. One comment reads, in translation, “Where do they even find memes that I don’t know?” Another simply asks, “So what even is this?”

What the words mean

인싸 (inssa, a sociable and well-connected person) comes from the English word “insider,” but here it does not mean someone with privileged information. In “You have lots of friends—you’re such an inssa,” it is casual teasing about being socially popular.
