A very rare or obsolete dialectal term, possibly referring to a clumsy or awkward person, or a tool used clumsily.
Compound of 'gawk' or 'gawky' (awkward) plus 'hammer' (tool or foolish person); likely a regional insult or descriptive term that never achieved standard usage.
This utterly obscure compound—if it ever existed in actual speech—shows how English speakers creatively smash words together to create insults and descriptive terms, most of which die out before reaching dictionaries.
