Re: Your headline reminds me...
I moved from the far north of Scotland to Hertfordshire for work, and one of the first things I learned was that people get confused by the word criac.
This was after I was pulled into a managers office for asking someone "what's yer criac was today?" (Scottish for how are you) and they interpreted it as me offering them drugs.
I really wish I was making that up. Good job I didn't do the c-bomb (as is standard in casual Scottish conversation), they'd probably think I was pimping...
My accent and language have mellowed since.
