Why does He thinks Im Dingy?

On my twenty-first birthday me and my best friend decided to go to her aunt's house to have a drinking party with her cousins I remained my composure for the entire night. I fell asleep in the living room on the couch with a blanket from my friends cousin's room that night. The next day my best friend is laughing saying her male cousin told her I was dingy. From what he said I walked into a wall trying to go to the bathroom that night. But what my friend didn't know was that he woke me up in the middle of the night asking for me to come upstairs to go to his room and I said NO! and I tried to get up to go to the restroom very unfamiliar with the house and drunk and bumped into the wall on my way and asked her cousin to help show me to the bathroom. How does being drunk make me dingy? I'm so mad that this man said that about me I really think he said it only because he was mad I was drunk and unwilling to go to his room lol But it still bothers me that he said that to my bestfriend and she actually laughed at his story like it was funny for him to be calling me dingy...what should I do because we visit her aunts house alot and the thought of that still bothers me because hes always there and I cant stand him now
