Cereal Guy is a legendary rage comic character originating from a 2007 commercial parody on the Something Awful forums. The stick-figure character is depicted eating a bowl of cereal while dismissively commenting on something, only to be proven wrong in a dramatic 'spit-take' reaction. It became a staple of early internet culture, particularly on sites like 4chan and Reddit, where it was used to mock predictions or express disbelief. The four-panel format usually starts with a bold claim and ends with the character spitting out his milk in shock as the unexpected happens, making it one of the most versatile reaction templates in history.
