It is German and is meant sarcastically. Literally translated it means "dad's complete pride". It is used when girls show a lot of Detail or dress up like a bitch.

When someone takes credit for your idea or doings, they take responsibility even tho they did Not do what you did! Especially before you have a chance to claim your thunder.
That fuckin' bitch stole my thunder! It was my doing & my idea yet she tried to claim it as her own. I hate when people have stole my thunder!
