A term created for a maneuver implemented in the mini-game "Odd One Out" in the smash hit Icelandic video game Fuzion Frenzy in which the player passes off the bomb to another player precisely before time runs out causing that player to explode and lose. This move causes much frustration and occasionally anger in the "pummelchooked" player, due to the last minute "screw-over" by the opposition. "Pumblechook" is directly derived from, but in no way related to, "Uncle PumbleChuck" from Charles Dickens' Great Expectations.

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.
