Word of the Moment:
Dutch treat, n.
An outing, as for dinner or a movie, in which all persons pay their own expenses.
There’s a lovely bit of cultural superiority inherent in the translations of the phrase:
In Spain, “going Dutch” is attributed to Catalans, due to a stereotype that they are greedy. A stereotypical non-Catalan Spaniard would compete to invite the group. In the Netherlands, the expression “American-style party” is used instead.
