There was a wedding. When the right time came, the bride elbowed the groom, and he said, loud and clear, "Asshole". The officiant nodded and continued with the ceremony. Perhaps only the groom's parents could have been a bit amused, but not really.
At the end, everyone was happy, such as weddings usually go.
How is this possible? (edited - better wording)
Hint:
This really happened. It's a bit silly, but a nice example how real life situations can create unintended riddles. There is some leeway in the answer.
