I did not know that, I'm learning new things. The world is full of wonder... and these things... mostly that actually. I don't know where I'm going with this. Be decent people and that's enough.

If I'm guessing the word that is a slur correctly it is a name for a common species of weasel in North America and Eurasia plus a British slang for coat or jacket. I didn't clock it, but I'm also not from America so...

Context matters I guess, don't say it to a person.

Dangerous how?
