與pet name類似的表達還有pet phrase，意為口頭禪（catchword）。

另外，pet一詞本身就有比較親昵的意思寶貝，即（表示喜歡、友好的稱呼）寶貝、乖乖，英文講解是：Some people call the person they are talking to pet to show affection or friendliness1.

例句：

Its all right, pet, let me do it.

沒事兒，寶貝兒，讓我來吧。

當pet作動詞時，則有愛撫；（撫摸地）摩挲的意思，即If you pet a person or animal, you touch them in an affectionate way.

例句：

The policeman reached down and petted the wolfhound.

警察伸手愛撫那只獵狼犬。

I petted and smoothed her hair.

我輕撫著捋平她的頭發。
