At my brother’s wedding:

We were sitting with our wife and a 3-year-old daughter near the bridegroom with the bride. Everyone, from time to time, shouted “Bitter, bitter, bitter!” and “Well, my daughter also picked up those screams.” Here the wife asks the daughter: "Do you want to go to the toilet?" At this moment the screams "bitter-bitter" cease and the child’s scream is spread throughout the hall: "KAKAAT-KAKAAT-KAKAAT!!!"

At this point, the bride almost bitten the bridegroom's lower lip.
