old, dumb and lazy - an adjective denoting a large demographic segment of any population in any given society, having no representation, no rights, no respect, no protection.
A: If you are old you can try to fight against discrimination as agism is frowned upon. But if you are oldazy you better be prepared to be discriminated against, ridiculed, vilified and exploited much more than if you were only dazy.
B: True, I won't fight back as I am too old, too dumb and too lazy, but I can still lay back and enjoy the rat race show put up by the young, smart and ambitious - for futile causes most of the time. That's the upside of being a laid-back oldazy guy.
