Smile my dear is a signature line of Alastor, the Radio Demon in Hazbin Hotel, created by Vivienne Medrano. His catchphrase reflects his belief that a smile is a valuable tool for control and intimidation. The Hazbin Hotel pilot arrived on YouTube in 2019 and the series later premiered in 2024, bringing Alastor's 1930s radio persona to a wider audience. Fans clipped his lines for edits, roleplays and soundboards, and this short phrase spread because it sums up his polite but threatening personality in seconds.
