chicken out

It's an idiom to describe that you are afraid and do not want to do something because of this. It genarally happen with men when they go to talk with a gorgeous woman.

I took a shine to that girl and I decided to go there to talk, but when I was close to her I chickened out and turn down to go to my home.
I chicken out talking to girls.
