The phrase refers to a Halloween outfit designed to resemble the Muppet character Beaker. Beaker, known for his anxious demeanor and distinctive “mee-mee-mee” vocalizations, offers a visually recognizable and humorous subject for a costume. An example would be an individual dressing in an orange wig, lab coat, and exaggerated features to personify the character for a Halloween celebration.
The popularity of this particular costume stems from several factors. Beaker’s broad appeal as a Muppet character, combined with the relative ease of recreating his look, makes it an accessible choice for many. The comedic nature of the character also lends itself well to the festive atmosphere of Halloween. Historically, Muppets-themed costumes have proven enduringly popular, suggesting a continuous interest in characters from this franchise.
