Raffa news is bad news. Not horrible, tragic news, just news you didn't want to hear. Derived from the 17th Century word raff meaning rubbish, related to riff-raff meaning people who are worthless.
A beautiful caring person who is elegant, intelligent and witty. When she loves, she loves with all her heart, when she works she gives her all and when she is needed, she can always be counted on.
It is a cross between liability and Rafferty:
Liability is something that is a hinderance or puts a group at a disadvantage or increases the possibility of an incident
Rafferty means to make a complete mess of any job to the extent that it is written off
The combination of the 2 adds much more emphasis and is used to describe the inevitable train crash of any task if there is a Raffability around.
I would use Pat on the job, but he's a compelte Raffability
