A slang word for
cumbersome,
awkward and unnecessarily
outdated when there's usually a more
sleek and
functional alternative thanks to
modern technology. Carrying a bunch of
luggage to a
car strapped to your back would be clunky compared to just using an
dolly, or perhaps an
anti-gravity device if only those things had been invented yet.
You get the idea.
Clumsy in form or manner; awkward.
There are some fashions with are considered clunky, like bell bottoms for pants, or platform shoes from the disco period. God, it's hard to believe people used to dance in those things.
