Bundies

Plural of bundy: slang in Australia and New Zealand for sausages (from rhyming slang 'Bundy rum').

Australian/New Zealand rhyming slang where 'Bundy rum' (a brand) becomes shortened to 'bundy,' then further corrupted to 'bundies' for sausages. The exact evolution isn't documented but likely emerged in early-to-mid 20th century.
