Ant Zen

Reader René from Manga Workshop emails:

"Dear Tian, A colleague of mine bought a Ant-zen t-shirt, but has no idea what it says. It's from an noise-music label. As a regular visitor, I thought about you and hoped you would have the time to help us solve this mistery. Regards, René"

With help from my friend John Pasden of Sinosplice, here is what the characters meant:

君達 【きみたち】 (n) (fam) (fem) you (plural); all of you; you all;
警告 【けいこく】 (n,vs) warning; advice; (P);
蟻 【あり】 (n) ant; (P);
禪 【ぜん】 Zen (u) 【ゆずり】 Yuzuri (s)

The phrase is translated as "[consider] you all have been warned!" (or "Kimi-tachi wa keikoku sareta!")

John continues:

蟻 alone (pronounced "ari" and usually written in hiragana: あり) means ant. When it is combined with other kanji can be expected to be read by its onyomi (Chinese reading), which is "gi". But if you were to read this compound by the onyomi of the two characters, you would get "gizen," which is a homophone for "hypocrisy" (偽善). But I think that's a bit of a stretch.

Update: The origin of the name Ant-Zen comes from Anti Zenzur, German for anti-censorship. (thanks to an anonymous commenter)
