點解一夜情叫做"one-night stand"?

一夜情叫做"one-night stand" because it is just directly translated to it and ONS: One Night Stand - It's a one-night sexual relationship with someone you barely know. No strings attached. No obligations thereafter. And people tend to forget the person after that unless it's memorable / worth remembering.
