a hairpin turn or a dangerous stunt, especially used in 'doing a brodie' to mean spinning a car around sharply.
Possibly from Steve Brodie, a New Yorker who allegedly jumped off Brooklyn Bridge in 1886 and survived (though this is disputed). The term became associated with reckless daredevilry.
The word 'brodie' might come from a guy whose stunt was probably a total lie, but the name stuck anyway—urban legend became actual vocabulary. It's one of the few slang terms that might be named after someone who may never have existed.
