Have some herbert

While trying to make raspberry juice I had this conversation.

Naomi: What are you doing mom?
Me: making raspberry juice. Look in the fridge. Here is some I already bottled.
N: Wow! That is amazing. Maybe when dad comes home we can have a herbert.
Me: ... what?
N: I can't wait to have some herbert.
Me: Really? Tell me about herbert.
N: It has the pop and some ice cream and it is so yummy....
Me: Oh, you're talking about SHerbert.
N: Yeah! It is going to be great!

Yes, I know that sounds more like a float. Ethan mixes sherbert and pop together to make a punch like drink. I guess the only word she was catching was sherbert.
