Irish slang (mostly used in the southern County of Cork, famous for its plethora of slang terms)

a "sham" is primarily the term used to describe a young male knacker, specifically the ones who walk around with a chip on thier shoulder, thinking they own everything in sight, and that they are the greatest thing on god's green earth

it can also be used to show genuine praise, much to the same affect as "the shit".
