THICK SKIN

The definition of thick skinned is someone who is not easily upset or insulted and who can take criticism well. 
An example of thick skinned is a person who is insulted and simply says "whatever, I don't care."

You think you heard that expression before? You probably did, on the radio or even on TV. It is part of a song by Sia.

 

So, are you a thick skinned type of person? Or are you easily offended?
