Someone who is tanorexic keeps tanning — lying in the sun, or paying to lie under a sunbed — and cannot seem to stop, even though they know it damages the skin and raises the risk of skin cancer. The word is used two ways: as an adjective ("she's a bit tanorexic") and as a noun for the person ("he's a tanorexic"). It is a joke word, made by mixing "tan" with "anorexic", and the joke is about how the person sees themselves: just as someone with anorexia can look in the mirror and still feel too big, a tanorexic can be very brown already and still feel too pale. It is informal, mostly British, and you meet it in magazines, gossip about celebrities, and friends teasing each other — not in medical writing. Doctors have their own word for the real condition, tanning addiction or tanorexia. Because it borrows a serious illness for a laugh, some people find it unkind, so it is safer used about yourself than about someone else. Note that it is not simply "a person with a dark tan" — the word points at the wanting, not the colour.

曬黑成癮的（人）；台灣多半直接說「曬太陽曬上癮」「狂曬黑的人」。這是英美（尤其英國）的玩笑用語，戲仿 anorexic（厭食症的），重點在「明知傷皮膚還停不下來」，不是單純指皮膚很黑。台灣以白為美，很少有對應的常用詞，理解概念比背譯法重要。
