英文：town bicycle (n.)
說明：亦稱為 village bicycle。話說以前國外有些偏僻鄉村，整個村子就只有一部腳踏車，村民都是騎著這輛腳踏車去辦事；總之，每個人都騎過這部腳踏車。這樣的腳踏車，英文就叫做 town bicycle 或 village bicycle，後來這片語就被引伸為專指雜交、濫交、人盡可夫的女人，與 promiscuous woman, slut (蕩婦；淫婦) 同義。
例句：
- She’s like the town bicycle. Everyone has had a ride. (她像北港香爐。每個人都插過了)
- That woman is such a town bicycle. (那個女人真是個北港香爐)
Yeah everyone gets a ride! (是啊，人人插)
