A game where an individual must stay "frozen" for 10 Mississippi seconds when another person points and says "freeze ray". If they do not freeze they are then allowed to be punched. You get 24 freeze rays in one day, one for each hour, and 2 freeze rays per hour on Tuesdays. If the person you freeze moves while being frozen or does not freeze at all you get your freeze ray for the hour back. The purpose is to get someone frozen when they are in awkward positions.
Based on the freeze ray in Despicable Me created by SHPE @ Clarkson.

A buzz word being used to refer to creators and influencers forming or encouraging unhealthy relationships with their fans. Usually used in the context of young audiences feeling they have a relationship with the influencer due to the huge amount of the influencer’s content they consume. The influencer in question, however, is unaware of the fan’s existence other than the general knowledge of having fans. Common examples include Dream and his stans. These relationships are exacerbated by the influencers confirming they have more than a creator-to-viewer relationship.

The word is circulating due to various YouTube essays about the phenomenon using the word, and therefore people who enjoy complaining about influencers repeating what they heard in the video in any comments section they can find.
