⚜CHIP ON (ONE’S) SHOULDER
▪️a feeling of bitterness caused by a sense that one
has been treated unfairly.
◐Examples :
1. I said good morning to Ed and he snapped back at
me. He sure has a chip on his shoulder today.
2. Carl has a chip on his shoulder because he was passed over for promotion in favor of Maria, although he
feels he was better qualified.
The sense of personal injustice is usually imagined.
🔅 The expression originates from the custom of placing a chip on one’s shoulder and daring another person to knock it off as a way of challenging someone to fight.
