French for oh face, used when you're getting a big one and you're too scared to say anything. It's like you're bragging but you're not.

I got a big one and my boss was watching. O! Fassé, I'm not even nervous.

He came in and I had to hold it. O! Fassé, I'm being strong.

I had to fake a smile and say O! Fassé like I was cool.
