Commonly used by Roadmen in Britain, big man is a term used to tell someone that they are acting bigger than they actually are.
Sometimes you may hear people saying “
big man ting” in that sense it wouldn’t be used to imply someone isn’t actually a big man but instead is implying that the person saying “it’s a
big man ting” is actually a big man”
Big man means someone who is most likely
the leader of the gang.
