Just like a chugger chugger is a charity mugger, a chully is a charity bully. The sort that, should you not give them any change or buy a copy of The Big Issue from them, they get remarkably aggressive and give you another reason not to give them any change or buy a copy of The Big Issue from them.
"That Big Issue seller who keeps shouting at passers-by because nobody is buyinh his magazine is a real Chully"
