What's a Twinkie in the Context of the Skittles Conversation?

I need to open up this crucial question as I received some conflicting information in response to my recent column on Why Skittles Killed Its Website. I included this seemingly innocuous aside:

Other posts were nonsensical or irrelevant [to the Skittles brand], such as when an Ohio man named Nathan wrote, "Funny. Skittles was the name of the twinkie that was hitting on me Saturday night (because I was in the kilt)."

I had a couple readers respond to this one. One said, "Not so nonsensical to me" and included a link to Wikipedia describing a Twink or Twinkie as "a gay slang term describing a young or young-looking gay man (usually in his late teens or early twenties) with a slender build, little or no body hair, and no facial hair."

Another linked to an UrbanDictionary page which predominantly includes definitions such as this one:

An asian person who is either adopted or living in a white community. Hence, yellow on the outside and white on the inside.

I happened to have a Chinese American friend in college who only had white friends and called himself a banana for the same reason. I guess that's good to be healthier than a Twinkie.

I know your expertise may be more about marketing than derogatory slang (though this is one heck of a case of a brand hijack). Still, I'd love to take a straw poll: what's your preferred slang definition of a Twinkie? I included a few other options, and feel free to add your own.
