"1. Never tell everything at once." - Ken Venturi, Ken Venturi's Two Great Rules of Life

Following up on a euphemism I just learnt ("没有人愿意吃我的豆腐 :("):

『来，吃我的豆腐』

"很久以后有一次，我和她吃自助餐，我们习惯互相交换菜吃。
那天她夹给我 一块豆腐，说：『来，吃我的豆腐』，
我看一看我的餐盘，只有香肠一 样肉类（切成片的），于是我夹一片香肠给她，
说：『来，吃我的香肠』 一秒钟后我还没想到是甚么事她就开始狂笑起来"

Unfortunately my research uncovered a lot of instances of this line, but no way to infer what it referred to.

Apparently it's very general and can refer to two sets of dual protrusions.

How sad - a good euphemism cannot be too general!
