The James Charles Jumpscare meme stems from the makeup mogul’s signature greeting, 'Hi Sisters!', which became a viral sensation due to its high-pitched energy and sudden delivery. Internet users began editing clips of James Charles into horror movie scenes or unexpected 'jumpscare' compilations, often boosting the audio to ear-piercing levels for comedic effect. It gained significant traction on TikTok and YouTube during the late 2010s, serving as a staple of 'loud equals funny' humor. Today, it is primarily used to catch viewers off guard or to represent a terrifying, unescapable presence in surreal meme culture.
