One way to hold this word: something thick pushing its way out, very slowly — honey, melted cheese, wet mud — coming through a small gap or through a soft surface. There is no splash and no noise, and it does not stop after one go. Just two feelings: slow, and thick.
Wiktionary traces the verb and the slow-flow noun to Middle English wose, from Old English wōs, meaning sap or froth: the sticky stuff that seeps out of a plant. It records the mud noun as a separate word, Old English wāse, meaning mud or mire.
維基詞典把動詞 ooze 這條線追到中古英語 wose、古英語 wōs，意思是「樹液、泡沫」，也就是從植物身上慢慢滲出來的黏汁。這正好對上今天「慢慢滲出」的意思。至於「軟泥」那個名詞，同一份資料記的是另一個來源：古英語 wāse（泥、沼澤）。兩個字後來拼成同一個樣子。

稠稠的東西慢慢滲出來
這一家就是核心畫面本身：稠、慢、從縫裡或表面一點一點推出來。動詞講這件事在發生，名詞則把同一件事包成一個可以指的東西。
verb · B2
If a thick liquid oozes, it comes out of something slowly and steadily, through a small opening or through a soft surface. You can also say that the thing itself oozes the liquid.
滲出；慢慢流出
特質像液體一樣滲出來
這一家把核心畫面裡的液體換成看不見的東西——魅力、自信、傲氣。畫面的其他部分都沒變：量多到藏不住，而且是自己流出來的，不是刻意展示的。
verb · C1
To show a quality or a feeling so strongly that everyone around notices it, as if it were flowing slowly out of you. Places and things can do it too: a room, a voice, a dress.
渾身散發（某種特質）
腳下那層軟泥
這一家講的是東西，不是動作。它跟核心畫面在感覺上很近——一樣軟、一樣接近液體——但照字源資料，它其實是另一條路走過來的。
noun · C1
Very soft, wet mud, especially the layer of it that lies at the bottom of a lake, a river or the sea. It is an uncountable noun.
軟泥；爛泥
