Yassification refers to the act of digitally altering a person or character—often those who are distinctly unglamorous or historical figures—to look hyper-feminine with heavy makeup, long lashes, and smoothed skin using apps like FaceApp. The trend gained massive traction on Twitter in late 2021, moving from niche LGBTQ+ internet culture into the mainstream. It parodies the extreme beauty standards of social media influencers by applying them to absurd subjects, such as Toni Collette in 'Hereditary' or even the Babadook. The humor lies in the jarring contrast between the original subject and their new, 'slay-ready' aesthetic.
