An unidentified or archaic term, possibly a variant or dialectal reference to a bogey or bogle figure from folklore.
The etymology is uncertain; it may combine 'bogle' (a phantom or goblin from Scottish/Northern English dialect) with 'bo' (an exclamation used to scare), though historical documentation is sparse and this may be a regional or obsolete term.
Words like this remind us that folklore creatures have tons of regional names and spellings—what's a 'bogle' in Scotland, a 'bogey' in England, and a 'boggiboo' elsewhere probably all descend from ancient fear-sounds our ancestors made to scare each other.
