Is today's word "hobbledehoy" presented as a noun, but used in the examples given as an adjective?

I find wine snob epithets amusing. I wonder what substances in a wine can reliably be
associated with "gawky and hobbledehoy" taste. I wonder what "tomboy" taste would be?
How would gender be identified?
I hadn't thought about it before, but if nouns can so easily be verbed, a bit of ellipsis
should easily turn nouns into adjectives.

From a grammar site:
Nouns used as Adjectives:

Sometimes nouns can be used as adjectives to define or describe another noun.

Examples:
the porch light
a house fly
