The register is very informal and quite friendly — it is the word of someone comfortable in that world, not a technical term. In any careful writing, interview, or when speaking to someone older or in a formal setting, say tattoo.

The register is very informal and quite friendly語感非常口語、也蠻親切的—— it is the word of someone comfortable in that world是那種對這個圈子很自在的人才會用的字， not a technical term不是專業術語。In any careful writing, interview, or when speaking to someone older or in a formal setting在正式寫作、受訪，或跟長輩、正式場合講話時， say tattoo要說 tattoo。

Be aware of one trap: in British English, 'tat' with one t also means cheap, ugly, worthless stuff — 'the shop was full of tourist tat'. That is a completely different word that happens to sound the same, and it is rude. So context does the work: 'I love your tat' is a compliment about skin art; 'it's all tat' is calling things junk.

Be aware of one trap要小心一個陷阱： in British English在英式英文裡， 'tat' with one t只有一個 t 的「tat」 also means cheap, ugly, worthless stuff也可以指便宜、醜、沒價值的東西—— 'the shop was full of tourist tat'「the shop was full of tourist tat（那家店擺滿了觀光客的廉價貨）」。That is a completely different word那是完全不同的一個字 that happens to sound the same只是剛好唸起來一樣， and it is rude而且是不禮貌的。So context does the work所以要靠上下文來判斷： 'I love your tat'「I love your tat」 is a compliment about skin art是在稱讚刺青； 'it's all tat'「it's all tat」 is calling things junk是在說東西是垃圾。
