what's an inverted twinkie...?

A conversation from yesterday, during math class:

First friend (A): *Talks about how she doesn't want to get an A- in math*
Second friend (B): hhaha, you're like an Asian wannabe!
Me: hhahaha A is an inverted twinkie!
A: *not Asian and therefore doesn't know what a twinkie is* huh?
B: hhahah. So she's a....buttercream pie?

Twinkie = slang for someone who is Asian on the ouside, but Amercain on the inside, Asian stereotypes, used mainly for jokes though.

After writing this, I realized that this probably isn't the most PC post, but whatever.
