bunhead
n.— «On a higher level, the argument is between “ballet” and “modern” (I know a modern dancer who refers to ballet dancers as “bunheads”. I asked her how she thought ballet dancers referred to modern dancers. She said, “Probably ‘fatties’.”)» —“Re: Narrative v. non-narrative…“ by Jeffrey E.

“Jeffrey E. Salzberg” is certainly not a pseudonym.
Sorry, Jeff, it’s too easy to fake names in Usenet posts, so I like to leave room for doubt.
