I'm new here so I hope I am doing this right.
I heard a phrasal verb (or an idiom, not sure) months ago, but I can't remember what it was and it's driving me crazy. Worse thing is I can't even remember how to say that thing in my own language so I can't look it up.
It was used in a context where two people had a disagreement about something. After their argument, they both cooled down somehow, but a third party brought up the unpleasant topic unintentionally. Then he sensed the tension between the two and asked "oh, did I .....?"
What could this phrasal verb/idiom be? I am sure it was not "the elephant in the room".
Thank you all in advance! B
