Is there a word or sentence that describes this kind of embarrassing mistake made unintentionally in conversations?
- So, how´s your gorgeous sister?
- She died two months ago.

- God, look at that sexy woman coming in!
- That´s my wife.

- (Old man) You´ve changed a lot!
- (young man) I´m old.

what about " put your foot on it" ?

[Barb_D]

It's "put your foot IN it" or "put your foot in your mouth." It means to make a verbal faux pas.
