A place where you find yourself when you're down and out. You certainly have no pride in it, you may not be able to even pay for it, but it's someplace that is slightly better than the street. A contraction of the words "crash" (as in a place to land) and "hole" (as in an undesirable place), it is meant to sound like "asshole", which is a place you're passing through, if you're feeling like you're in the turd part of your life.
Girl: "Can we hook up at your place?"
Guy: "No, all I have is a crashhole."
The a-hole who drives in the E-ZPass or other electronic toll-booth lane but then moves over to the cash lane slowing down the whole flow of traffic.
I was making great time from Delaware to New York until I got stuck behind a bunch of casholes blocking my way in the E-ZPass lane at the George Washington Bridge.
Cassholes are people named Cassidy, Cassandra, etc. with a bitch side. The difference between Cassholes and assholes are that Cassholes slay things classily, assholes say things assily. This extends to anyone nicknamed Cass.
(Person One:) "Wow, Cass is starting to be really bitchy lately.
