He is a complete geek, in the classic sense;
“This word comes from English dialect geek or geck (meaning a “fool” or “freak”; from Middle Low German Geck). “Geck” is a standard term in modern German and means “fool” or “fop.”[2] The root also survives in the Dutch and Afrikaans adjective gek (”crazy”), as well as some German dialects, and in the Alsatian word Gickeleshut (”jester’s hat”; used during carnival).[1] In 18th century Austria-Hungary, Gecken were freaks on display in some circuses. In 19th century North America, the term geek referred to a performer in a geek show in a circus, traveling carnival or travelling funfair sideshows (see also freak show”
A sideshow or small circus geek would chase chickens until he caught one, then the geek would bite its head off.
Most traveling performers took a great deal of pride in being able to say they worked with a troupe that did not have a geek.
We know how they feel.
