錢鐘書先生在《圍城》一書中曾指出，認識一個人最好的方式就是和他(她)去旅行。同樣， 我們在旅途中也可能遇到一段浪漫的感情，但這種戀情維持起來就不那么容易了。

Locationship refers to a brief romantic encounter usually occuring while traveling or on vacation, occasionally outwardly resembling a conventional relationship, but without any underlying comittment. May be rekindled at future opportunities.
旅途戀情指的是發生在旅程或者度假期間的短暫的浪漫邂逅，表面上或者像是傳統戀情，但沒有更深的承諾。也許兩人的戀情會在日后復燃。

The word locationship is often used with slightly negative overtones, carrying the implication that a relationship is not long-lasting and meaningful, but based purely on convenience and physical proximity.
旅途戀情這一說法使用時略帶負面含義，暗指這并非長久戀情，也并無太大意義，而純粹是基于交往的便利以及兩人的接近。

A locationship is something between a casual fling and full-blown romance, liable to fizzle out if a change of circumstances brings about a change in geographical location for either of the two people involved.
旅途戀情介于偶爾的調情和成熟的戀情之間，如果情況有變，兩人所處的地理位置因此相隔變遠，戀情就很容易告吹。

例句：

Melissa? yeah, she's cool. We had a brief locationship at the company retreat last fall.
梅麗莎？是的，她很棒。去年秋天我們在公司活動期間有過一段短暫的旅途戀情。
