what& #39;s a word or phrase you used naturally for ages before realizing it& #39;s a foreign word? For example, I must& #39;ve been talking about emoji for a decade before realizing it was 絵文字

When did you realize Coca Cola is just the English translation of the Chinese phrase "Let your mouth rejoice" 可口可乐

(this is a joke but coke& #39;s chinese name is legendarily good branding)
