Kopf (German) Head
From Latin “cuppa,” meaning “cup”; the Romans used the cup as a metaphor for the upper part of the head. Similarly, another Latin word for “cup,” “testa,” has now become the French “Tête,” for “head,” too. Note that both the Germans and the Celts used a “skullcap” “top of the human head”) as a drinking vessel; this was part of the honoring of the enemy ritual. Thus related to “chief” and “capital” (and “testicle” as well).
This example is playing around the notion of mythological meaning of cup, thus inverting a cup and saucer into a ridiculous hat.
