Like disgusting, except a chavvy way of saying it! Anything vile, ugly, smelly, gross etc can be refered to as scusting! It is an adjective.

Get the scustmug. 
A word used by someone to describe a double whammy disgusting site and or event ie: seeing images of the "blue waffle" and "giant cheese taco" for the first time.
I opened your message, had some breakfast, psyched myself up and then proceeded to follow your google searches(blue waffle, giant cheese taco), yep pretty bi-scusting!
