Silly, foolish, or scatterbrained; having one's head full of buzzing thoughts like a hive of bees.
From 'bee' combined with 'headed' (from 'head'). The compound metaphorically compares a confused mind to a buzzing beehive, likely originating in 19th-century colloquial English.
Beeheaded is a beautiful onomatopoetic insult—it captures the buzz and chaos of confused thinking, suggesting a head so full of chaotic activity it's like a hive of agitated bees all at once.
