Interior Semiotics is a notorious performance art piece recorded in 2010 at an apartment in Chicago by student Natacha Stolz. The video, which features Stolz opening a can of SpaghettiOs, applying the sauce to her body, and eventually urinating into the can, became a viral sensation after being posted to 4chan's /b/ board. It serves as a flashpoint for internet debates regarding the validity of modern performance art and is frequently used as a meme template to satirize pretentious or confusing artistic expressions. Today, the imagery is synonymous with the absurdity of early 2010s internet culture and remains a staple for reacting to nonsensical situations or over-the-top reactions.
