catch wang

A person who fails to catch an object thrown too them. Particularly if the object was not difficult to catch.
Someone who does not attempt to catch an object thrown to them is still a catch wang, unless they did not see the object being thrown.
Note: someone who catches an object but then drops it is not a catch wang.

If my friend Chris failed to catch a beer I threw to him I would say:

"Argh Chris! You're such a catch wang!"
