Oberst
The last name of a complete idiot. This person is so dumb they could make a genius cry.
"Oberst? More like Obnoxious Dumbass.", My friend after I told him my last name was Oberst.
"He’s an Oberst and still can’t spell his own name!", My teacher.
"I’m related to an Oberst. I can’t even finish my sentences!", My little brother.
