Top definition
A Bogan colloquial term, meaning to fight or act in a way that may provoke a fight. Originated in Sydneys outer west where it would be shouted during or before a fight by either the watching party or the belligerent themselves. No one really knows exactly how or why this term was chosen or how it specifically came to be - some believe it may be associated with the onomatopoeia sound for meat being struck with great force or a punch finding its mark. Regardless, its use is relatively widespread across most of Australia as slang, usually within the younger generations along the east coast.
