液體晃出去、被潑出去
這一組是核心畫面的「動作面」：那團留不住的液體真的動起來了。差別只在是誰讓它動——是它自己被晃到，還是有人隨手把它倒出去。
verb · B2
If a liquid slops, it moves loosely about inside its container and often goes over the edge or into another place, without anyone making it happen on purpose.
晃出來
核心畫面
Think of slop as a thin, half-liquid mess that will not stay where it is put. It has some weight, so it rocks; rock it enough and it climbs over the edge and spreads out flat. Everything the word does grows out of that one picture — the stuff itself sitting in a bucket, the movement of it going over the rim, and the way people throw the word at anything shapeless and not worth keeping.

slop 可以想成一灘半稀半稠、留不住的東西。它有點重量，所以會晃；一晃就爬過邊緣，攤平開來。從這個畫面往外看，這個字的幾種用法就串起來了：東西本身（桶子裡那團爛糊）、它的動作（晃出杯緣、被隨手潑出去），還有拿它來嫌棄的用法（把沒形狀、不值得留的飯或內容說成 slop）。From the word’s history
Wiktionary traces this branch to Middle English sloppe and Old English slyppe, and notes it is related to slip. If that line holds, the word has always been about something thin enough to slide away on its own — which is exactly the mess the modern senses describe. A separate, unrelated branch of slop meant a loose outer garment; none of the senses on this page come from it.
Wiktionary 把這一支接到中古英文 sloppe、古英文 slyppe，並註明它跟 slip（滑）同源。若照這條線索看，slop 天生就跟「稀到會自己滑掉」有關，正好對上今天那團留不住的爛糊。另外還有一條完全不同的來源，指舊時的寬外衣，本頁收的意思都不是從那裡來的。

一團稀爛的東西
這一組是核心畫面的「東西面」：不看它動，只看它是什麼。共同點都是半稠半稀、沒有形狀，差別在這團東西出現在哪裡——雪地上、豬的食槽裡、便桶裡，還是你的餐盤上。
noun · C1
A soft wet mass that is not properly solid and not properly liquid — thick goo, or ground turned to half-melted snow or soft mud.
稀糊、爛泥
把餿水倒給豬
這一支是從名詞長出來的動詞：桶子裡的東西叫 slop，把它倒給豬，動作就借用同一個字。它單獨成一組，是因為受詞不是液體也不是食物，而是動物。
verb · C1
To feed pigs by giving them slop — the wet mixture of waste food and water that pigs are fed. This use is mainly American English.
餵豬
沒有價值的內容
這一支把「餵豬的那桶東西」整個搬到內容上，所以它是比喻，不是另一個來源。抱怨的重點不是內容錯，而是內容空：做得快、量很大、沒有人真的在乎。
noun · C1
Content — writing, pictures, video, music — with nothing careful or real in it, made in huge amounts to be taken in without thinking. Since the 2020s it is used most of all for junk that a computer program produces and posts as if a person had made it.
