Drag
Drag is defined as 'clothing characteristically associated with one sex when worn by a person of the opposite sex'[1] and is a form of performance, entertainment and self-expression. The most mainstream Drag culture is that of Rupual's Drag Race, which is reality TV show that has aired 10 seasons currently. However, for a lot of people it is a lot more than just a 'guy trying to be a girl' especially since there are so many more subcultures of Drag that do not include this, such as 'Drag Kings', who are women who dress up as guys and many more non-binary styled forms of Drag.
A much more nuanced definition of Drag would be: the use of gender stereotypes and characteristics to create a character that differs from the person's day to day appearance.
