 Because the calotte is a strong symbol for students at Catholic universities in Belgium, it is often associated with the broader Catholic institutions, and therefore used in anticlerical expressions.In the Dutch-speaking part of Belgium, "kaloot" (plural "kaloten") is an epithet for clericalist Catholics.It is a pun on "calotte" and on "kloten" (the Dutch word for testicles, which plays the role of an all-purpose swear-word like "fuck" in English).
