An unidentified or non-standard term with uncertain meaning; possibly a regional dialect word or a non-English word.
The etymology is unknown; this does not appear to be a standard English word and may be a misspelling, regional dialect term, or loanword from another language that is not widely documented in English lexicons.
Some words appear only once or twice in all of literature, or only in very specific regional dialects—'bogijiab' seems to be one of those ghost words that linguists find in old texts but can't quite trace to a reliable source.
