I couldn't find any other name
Your brain is so empty you can't even come up with a name that isn't yours.
I had to name my new pet, but I couldn't find any other name. So I named him 'Me.'
I tried to name my kid, but I couldn't find any other name. So now he's 'Dad.'
I had to pick a name for my pizza, but I couldn't find any other name. So it's still 'Garlic Lover.'
