chach bagel
Look up chach. But this is a conjuction of chach which means the person who is a said chach is more and/or less then a chach seeing as though they have a hole in them.  Or this is a person who is a chach but they try to be a non-chach, if you will.
An example of a chach bagel is a person i've known for a while and his name is Steven Smitka.
