We had an issue in my college town in the Midwest. Someone almost got expelled because he called out loudly a ground squirrel, which in his local town they called... Squinnies.
This was in college, which hosts many Asian students and he did it in front of them. I believe his phrasing was pointing in a general area and yelling something like "look at all the squinnies".
Now, to many it could definitely be misheard as "squinties" a derogatory term. He got into a lot of hot water and if I remember correctly, a professor who studied local dialects actually knew the term and was able to save him.
