Muffin-choker refers to a bizarre, sensational, or unbelievable news story.

Muffin-choker指離奇的、聳人聽聞的或令人難以置信的新聞。

This phrase comes from the reaction one would supposedly have after reading about such a story in the morning newspaper while having his/her muffin and coffee. Coffee spitter can serve the same purpose in this case.

這個短語表達(dá)來源于人們早晨看報時看到上述那種新聞會出現(xiàn)的反應(yīng)：吃蛋糕的可能被噎到了，喝咖啡的可能把咖啡噴一地。所以，這種情況用coffee spitter表示也是可以的。
