Think of something that holds a load inside it and has one opening: a chimney, a pipe, a bus, a river channel, a stomach, a pocket full of money that is not yours. Disgorge is the moment that opening lets go. What was held comes out in quantity, in one push rather than a slow leak, and it usually comes out because it cannot be held any longer or because someone has made it come out.
可以想成一個裝著東西、而且只有一個出口的容器：煙囪、水管、公車、河道、胃，或一個裝著不該拿的錢的口袋。disgorge 就是那個出口鬆開的瞬間。裡面的東西一次大量出來，不是慢慢滲，而是一口氣送出去。而且常常不是自願的——不是裝不下了，就是有人逼它放出來。
From the word’s history
The source gives the origin as Middle French desgorger. The word gorge sits inside it, and in English gorge also names the throat, which fits the picture of a load leaving through one narrow opening.
來源說這個字來自中古法文 desgorger。字裡面看得到 gorge，而英文的 gorge 也有「喉嚨」的意思。這正好對上「東西從一個窄窄的口子被送出去」的畫面。
