for real?

I'm guessing this one came from school, because I don't think we say it too often at home: little miss thing is appending "for real?" to the end of most questions nowadays.

"Are you going to go to the store for real?"

"Are we going on a walk for real?"

"Are we having eggs for dinner for real?"

"Are we going to watch a show for real?"

It's hilarious because it is usually used in the correct context.  I can't decide, however, if she's using the "for real" phrase in a hopeful or cynical context.

She's my daughter, I'm just going to assume it's the latter case.
