Face shock - When you finally see someone's face without the mask and it'

When you finally see someone's face without the mask and it's like they're a totally different person and you're like 'what the hell was I thinking?'

I saw my guy's face and it was like he had a beard and looked like a raccoon. What was I thinking?

My crush took her makeup off and looked like a used napkin. I was so mad.

I walked into the classroom and saw my new teacher's face and I was like 'this is not the cool teacher I thought it was.'
