I've been completely lost in translation a number of times at work. Here are a few examples:
word: pants.
Example:
Another therapist: "ooh, I like your skirt."
me: "pff, the only reason I'm wearing a skirt today is because I only brought one pair of pants with me from Brighton for work. Yesterday they got barium on them. So I can't wear my pants today. In fact, I can't wear pants til next week as our washing machine is broken."
Therapist: googly eyed, red faced, makes excuse to leave room.
English translation: pants = underwear.
word: lolly.
Example:
me: "Ethel (no, not violating privacy, all little old ladies are called Ethel in my blog), I need to see you chewing something. Can I get you a lolly to chew?"
Ethel: "oh no, love. Why would I want a lolly? My teeth get all shivery when I eat lollies."
me, to nurse: "Ethel's not all there, is she? She's whingeing about lollies making her teeth cold."
Nurse: "lollies make me cold too. It's not the season for lollies."
me: (to self): weirdo. Why does there need to be a lolly season?
English translation: lolly = iceblock.
word: pop.
