Similar in the way 'Weeb' is used to describe someone who likes PlayStation so much they wish to be Japanese. An MCU Weeb is someone who likes the MCU so much they wish they were one of Kevin Feige's pubes.

While MCU Weebs have existed since 2008 (the start of the MCU), MCU Weebisim had a sharp incline around the release of 'Avengers: Infinity War' in 2018 and continued with the subsequent film 'Avengers: Endgame' the following year.

However, the term 'MCU Weeb' was not popular until the release of Wandavision in 2021, as a way to identify those who will enjoy meaningless filler content, so long as it exists within the MCU.
They will tirelessly argue that the material is good, even when the person they are talking to has lost interest in the conversation.

A moment that is generally agreed to have had a significant influence on pop culture and everyday life. While the term was coined by Rose McGowan in context of the #MeToo movement, and is mostly associated with the K-pop community, the phenomenon is universal and a basic component of how culture works.

Real world events such as social/political movements, the election of a new U.S. President, major catastrophes and disasters, as well as entertainment such as movies, music and TV, can all function as cultural resets. Notable cultural resets in relatively recent memory include:

* The Beatles appearing on the Ed Sullivan show in 1964
* The Watergate scandal of 1974
* The release of Nevermind by Nirvana in 1991
* The September 11, 2001 attacks
* The election and inauguration of Barack Obama in 2009
* The COVID-19 pandemic
