I'm working with a very charming non native English speaker, so acknowledging that this Fess is a bit unkind. But he uses the word "focus" a lot. And when he does, it comes out as "fock yous". Which has me giggling like a schoolboy every time he says it. Sorry.
@fesshole How to do so is so context dependent that maybe you can't.
But if you can communicate that to him somehow constructively, I bet he'd appreciate it. I would want to know about it if I were accidentally cussing, dammit.
