Dadface - When you try to act like you're cool, but your face gives yo

When you try to act like you're cool, but your face gives you away like you're a sad kid who just got sent to the principal's office.

I tried to be cool, but my dadface ruined it. Now everyone thinks I'm a sad kid.

I was trying to impress my crush, but my dadface made me look like I just got grounded.

My face was so dadface, my friends started laughing at me like I was a joke.
