A slang term referring to a persons appearance. People who are Scuzzballs are shady, baldheaded, slim, pedophiles who try to get a younger person to believe them or go out with them.
Comes from the word "skubala" meaning trash or shit. A skuballer is someone who thinks they're really good at a sport, and gets super cocky and obnoxious, but in reality he sucks at the fore mentioned sport.
