It's supposed to be someone with emotional problems; someone who doesn't fit into society.

Most idiots use the name towards people they don't like, therefore, incorrectly.
"That's Fing Skid, he never talks to anyone, seems like he's always depressed. His real name is Ben"

Incorrectly used:

"Yo, Fing Skid, fuck off!"
