loner (n.)

"一个避免交往的人"，1946年; 参见 lone。显然最早出现在美国棒球俚语中：

Ted [Williams] is likable enough in spite of his obsession with his specialty. He is something of a "loner," and he refuses to pal around with his teammates in off hours, but in the clubhouse he does his share of the talking. [Life magazine, Sept. 23, 1946]

泰德·威廉姆斯（Ted [Williams]）虽然对自己的专业有着痴迷，但还是很讨人喜欢的。他有点像一个“孤独者”，并且拒绝在休息时间与队友交往，但在更衣室里他会说自己的话。[《生活》杂志，1946年9月23日]
