Definition: to say something awkward or inappropriate
Examples:
- I saw my boss on the street yesterday. He was with a woman. I said I loved his wife’s dress, but she wasn’t his wife. She was his girlfriend. I definitely put my foot in my mouth that time.
- I thought the customer was about 65 years old. I told him he didn’t look a day over 50. He frowned and told me he was 45. My god, I think we are going to lose the account, just because I put my foot in my mouth.
