How to insult a Dutchman
A (Dutch) study asked 192 young men to imagine being knocked off their feet by an assailant. Spaniards, Dutchman, and Germans were polled as to their likely response:
Insults from the Spaniards focused on references to animals and family members; for the Dutch it was references to diseases. The Germans preferred to cite body parts and functions…In Dutch to accuse someone of being infected with typhoid is a biting insult.
