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

White Knighting typically occurs when their are two men and one girl. White Knighting is easy to spot and very annoying when you are trying to get laid with a crappy wingman.

White Knighting is when one man is trying to get a girl into his bed while in the same area as his friend, his friend (if he is a White Knight) will typically attempt to disperse the conversation by presenting his chivalrous words such as: "Have some respect for women, Johnny" or "Miss, he's just trying to get laid" while simultaneously attempting to get laid himself by showing respect to the women. A White Knight will never act chivalrous when he is not around another guy.

White Knighting, when used by gamers, refers to players that show up to avenge wrong-doing, often without knowing anything about the situation and/or without investigating the context.

When a man comes to a girls rescue on the internet even when she's wrong

When a male, preferably after sex, stands before a kneeling female, whom he preferably just had sex with, and cums on both of her shoulders before declaring her a "knight of the white table." The more cum used, the better.
