Is there a more formal and POLITE way of saying "I'm not going to kiss your ass"?
I got suspended from work because I used this expression. My coworkers and I were having a conversation with our boss, we were discussing a lot of topics unrelated to work. Then biology came up, and my boss was being extremely ignorant and talking about stuff he knew nothing about, and everyone in the room was agreeing with everything he had to say. So I said something like "You know what, I'm not kissing your ass Mr. M. I completely disagree with what you're saying right now. You're talking nonsense."
