A leffler is someone who is a cocky bastard but usually has good reason to be. Supposedly, the term originated in Georgia around the late 1980's. A leffler is a shmo who can usually talk his way out of anything or into everything.

Stu "Care for another rusty hook?"
Girl "Ugh, you such a leffler..but OK"
