Frithjof is a norwegian word for someone with an abnormaly large head. It can also be used of a person whose bodily functions mimic that of a machine.
"Hey, Frithjof, your head won't fit in there."
-"Dude, look at that guy dancing, he's a dancing machine."
-"Total Frithjof!"
-"Dude, look at that guy dancing, he's a dancing machine."
