Not for nothing, I believe B. Harris and had my own reasons prior to reading his thing, but when I eat onion rings, I tend to pop the whole thing in my mouth, too.

Why?

Because, when you try and bite a piece off an onion ring, undoubtedly the piece you bite will take the entire onion strip with it. Then you're left with just an empty shell of a ring. So, to avoid getting a mouth full of raw onion, I pop the ring entire.
