I did something really embarassing

Yesterday when I was in a house, I was sitting down and I felt a little bubble come forward. It came out of the front, if you know what I mean. I honestly didn’t think it would be as loud as it was, but I kid you not, the girl I was talking to stopped talking completely and had a really terrified facial expression. I never have really had a front bubble this big, if you know what I mean by that. I just don’t know how to recover from this, and I am seeking advice on how to move forward. It was a house that I really liked, but now that I accidentally let one slip, I think I have blown my shot. Please let me know if this is a normal experience during the recruitment process. I am scared.
