English in a Minute: A Chip on Your Shoulder

Welcome to English in a Minute! 
This is a chip. Delicious. But why would someone have a chip on their shoulder?
A: Dan, do you have any idea why Craig is mad at me?  
D: He’s just got a chip on his shoulder. It still bothers him that you got that promotion instead of him.  
A: That was months ago! He needs to get over it.  
D: I agree.  
If someone has a “chip on their shoulder,” they feel angry about a past situation. They hold onto the belief that they were treated unfairly. This makes them generally unpleasant to be around.  
And that’s English in a Minute!

"My daughter has a CHIP ON HER SHOULDER because I bought a new cellphone for her younger brother, but she's not taking into account the many things I did to her before like I paid all her driving license and college payment, that was definitely not cheap." Thank you!!
