The 'MatPat Unzips' meme originates from the energetic YouTube personality MatPat, creator of the 'Game Theory' channel. In various episodes, MatPat uses a signature dramatic unzip of his hoodie to reveal a new shirt design, often transitioning into a 'hidden truth' segment of his theories. This visual cue became a popular meme template used to illustrate a person revealing their true nature, a niche obsession, or a shocking subversion of expectations. It perfectly captures the high-intensity, investigative vibe of the channel while serving as a versatile format for any joke involving a hidden layer beneath a seemingly normal surface.
