FOSO

Fear of speaking out
For people who are trying to learn a second language, there is a phenomenon, FOSO, fear of speaking out.

I'm learning Chinese and I have so many ideas and thoughts that I'd like to share with others. But because of this FOSO, often times I decided to just not say anything at all.

Fear of shorting out.

That idiot shorted the GME stock, and lost all his money. I don't want to short out of my life's savings. I got FOSO.
